As shown in fig. 1, the invention provides a method for optimizing a transcritical carbon dioxide centrifugal compressor, wherein the method for optimizing the transcritical carbon dioxide centrifugal compressor comprises the following steps: the physical property interval of the transcritical carbon dioxide is equivalent to the physical property interval of an ideal working medium based on a fluid similarity theory; performing geometric parameter sensitivity analysis of the centrifugal compressor according to the ideal working medium, and screening out the geometric parameter value with optimal power consumption of the centrifugal compressor of the ideal working medium; and (3) the geometrical parameter value with optimal energy consumption of the ideal working medium centrifugal compressor is retracted back to the transcritical carbon dioxide centrifugal compressor according to the fluid similarity theory, so that the geometrical parameter value with optimal energy consumption of the transcritical carbon dioxide centrifugal compressor is obtained.
According to the optimization method of the transcritical carbon dioxide centrifugal compressor, the physical property interval of transcritical carbon dioxide is equivalent to the physical property interval of an ideal working medium, and the physical property of the ideal working medium does not change rapidly in thermal cycle, so that the problem of rapid physical property change in the transcritical carbon dioxide area is avoided, and then the geometric parameter sensitivity analysis of the centrifugal compressor is carried out according to the equivalent ideal working medium, and the geometric parameter value with optimal power consumption of the ideal working medium centrifugal compressor is screened out; and finally, the geometrical parameter value with optimal energy consumption of the ideal working medium centrifugal compressor is retracted back to the transcritical carbon dioxide centrifugal compressor according to the fluid similarity theory so as to obtain the geometrical parameter value with optimal power consumption of the transcritical carbon dioxide centrifugal compressor, thereby solving the problems that the transcritical carbon dioxide centrifugal compressor fails in optimal design due to rapid change of physical properties and cannot be rapidly and efficiently subjected to parameter sensitivity analysis so as to obtain the optimal design parameter of the transcritical carbon dioxide centrifugal compressor, and providing technical support and guarantee for efficient research and development of the transcritical carbon dioxide centrifugal compressor of hundred kilowatt-level to megawatt-level and efficient operation of the transcritical carbon dioxide circulation.
In an alternative embodiment of the invention, as shown in fig. 2, the geometric parameters include the centrifugal compressor blade root diameter 6, the impeller outlet diameter 7, the impeller inlet gap 8, the impeller outlet gap 9.
In an alternative embodiment of the invention, the isentropic efficiency of the transcritical carbon dioxide is obtained by scaling according to an approximate empirical relationship, which is the following:
（1）
wherein ,is the ideal working medium expansion index +.>For the trans-critical carbon dioxide expansion index, < >>Is the diameter of the inlet of the centrifugal compressor with ideal working medium +.>The diameter of the inlet of the compressor is the diameter of the inlet of the transcritical carbon dioxide centrifugal compressor.
In an alternative embodiment of the invention, the geometric parameter sensitivity analysis is performed based on a central combination design and a DOE test scheme, namely, the geometric parameter sensitivity analysis of the root diameter 6, the outlet diameter 7, the inlet gap 8 and the outlet gap 9 of the centrifugal compressor based on the central combination design and the DOE test method is performed according to an equivalent ideal working medium.
It should be noted that, the DOE (Design of Experiments) experimental design is to analyze the fitting relationship between the input variable and the output variable by using a mathematical statistics method, so as to determine the key test factors and the preferred parameter combination scheme. In the present invention, the details of the DOE test protocol are shown in table 2.
In an alternative example of this embodiment, the DOE test scheme uses a one-dimensional calculation method as a reference for pneumatic evaluation, specifically a 2D mean line method, i.e. a centrifugal compressor speed triangle diagram under consideration of various loss models is used to predict the variation of the centrifugal compressor operating conditions.
In an alternative example of this embodiment, the center combination design takes a four-factor five level. The four factors are blade root diameter, impeller outlet diameter, impeller inlet gap and impeller outlet gap; five levels are five levels of +/-30 percent, +/-15 percent and 0 percent based on the standard geometric parameters of the equivalent ideal working medium.
Specifically, when data analysis is performed, a four-factor five-level encoding table is generated (see table 1).
Table 1 four-factor five-level encoding table
In an alternative example, see table 2 for specific protocols for DOE experiments.
Table 2 test protocol
Furthermore, in order to ensure that the compressor impeller and the air cylinder are not in collision and abrasion in the actual process of engineering, the reference values of the impeller inlet gap and the impeller outlet gap are not lower than 0.36mm so as to ensure that the minimum gap value in the test scheme is not lower than 0.25mm. In an optional embodiment of the invention, the optimal geometric parameter value of the ideal working medium centrifugal compressor is screened out according to the contribution rate of the geometric parameter to the performance index and the main effect analysis.
In an alternative example of this embodiment, the performance index is compressor power consumption of the centrifugal compressor.
Further, the compressor power consumption includes pneumatic power consumption and wind power consumption of the compressor.
Preferably, the pneumatic work consumption is defined as follows:
（2）
wherein m is the mass flow rate through the compressor, h out,s Is the enthalpy value of the isentropic outlet of the compressor, h in The compressed air is the enthalpy value of the inlet of the compressor,is the pneumatic efficiency of the compressor.
Preferably, the wind power consumption is defined as follows:
（3）
wherein , is windage loss system->For the rotation angular velocity +.>For the impeller outlet diameter>Is the rotor diameter.

Preferably, the centrifugal compressor inlet gas flow is located in the region above the saturation line.
Preferably, the inlet airflow limit flow velocity v of the centrifugal compressor limit And the limit sound velocity alpha limit The ratio of the inlet air flow limit velocity v of the centrifugal compressor is more than or equal to 0.3 limit The definition is as follows:
（4）
in the formula ,h0 Is the isentropic stagnation total enthalpy of the inlet airflow, h limit Isentropically expanding the inlet airflow to an enthalpy value at a saturation line, wherein the sound velocity corresponding to the enthalpy value is a limit sound velocityα limit 。
It should be noted that, the inlet air flow of the transcritical carbon dioxide centrifugal compressor is above the saturation line, and the inlet pressure is as high as above 5MPa, so the attribute of high density in this state is one of the important characteristics of the transcritical carbon dioxide centrifugal compressor; on the other hand, the high density property of the transcritical carbon dioxide can increase the rotating speed under the same compressor design rule, so that the characteristic of high rotating speed caused by high density is another important characteristic of the transcritical carbon dioxide compressor. Meanwhile, the wind power consumption of the centrifugal compressor is in direct proportion to the third power of the rotating speed and the density, the diameter of the impeller outlet is in direct proportion to the fifth power of the impeller outlet, and the diameter of the impeller outlet 7 is also an important influencing factor in the optimal design scheme, so that the comprehensive consideration of the pneumatic power consumption of the compressor and the power consumption of the compressor after wind power consumption has very important engineering significance.
In an alternative example of this embodiment, the contribution rate size is determined by comparing Pareto graphs. And determining the geometric parameter value and the optimal parameter value combination which affect the maximum aerodynamic performance of the equivalent ideal working medium centrifugal compressor according to the contribution rate of the impeller root diameter 6, the impeller outlet diameter 7, the impeller inlet gap 8 and the impeller outlet gap 9 in the Pareto diagram and the analysis of the main effect diagram.
In the invention, a fitting method adopted in the optimization method of the transcritical carbon dioxide centrifugal compressor is a quadratic polynomial fitting method, the value range of an input variable in a fitting formula is normalized to [ -1,1] to obtain the variable coefficient of each item again, and then the contribution rate of the item in the Pareto chart can be obtained by comparing the variable coefficient of each item with the sum of absolute values of the variable coefficients. As shown in fig. 3, the Pareto plot reflects the percentage contribution of the different terms in the fitted model to each response, with the left side representing the negative effect and the right side representing the positive effect.
According to the optimization method of the transcritical carbon dioxide centrifugal compressor, transcritical carbon dioxide is equivalent to a physical property interval of an ideal working medium based on a fluid similarity theory, so that the problem of rapid physical property change of the transcritical carbon dioxide area is avoided, then geometric parameter sensitivity analysis based on a central combination design and DOE experiment method is carried out on the centrifugal compressor blade root diameter 6, the impeller outlet diameter 7, the impeller inlet gap 8 and the impeller outlet gap 9 according to the equivalent ideal working medium, then an optimal geometric parameter value of the centrifugal compressor is determined according to the compressor power consumption contribution rate and the main effect analysis of the geometric parameters, and finally the optimal geometric parameter screened out by the equivalent ideal working medium is retracted to the transcritical carbon dioxide by means of the fluid similarity theory, so that the optimal geometric parameter value of the compressor power consumption of the transcritical carbon dioxide area is obtained.
The optimization method of the transcritical carbon dioxide centrifugal compressor can solve the problems that the optimal design of the transcritical carbon dioxide centrifugal compressor is invalid due to rapid physical property change and parameter sensitivity analysis cannot be performed rapidly and efficiently so as to obtain optimal design parameters of the transcritical carbon dioxide centrifugal compressor, and provides technical support and guidance for efficient design of the transcritical carbon dioxide centrifugal compressor and efficient operation of transcritical carbon dioxide circulation.
