A pressure and mechanical coupling type atomizing nozzle swirl control method comprises the following steps:
step one, establishing a neural network model
The BP neural network model is based on a great number of sample points to gradually mine the potential relation between known input and output, and the invention provides sample data for the establishment of the neural network model through simulation. Taking the pressure of fluid introduced into the pipe joint, the viscosity of the fluid and the rotation coefficient of the spinning disk as variables, and obtaining sample points of a plurality of groups of variables as input layer vectors;
the parameters influencing the atomization diffusion performance of the atomizing nozzle are more, the atomization performance of the atomizing nozzle is comprehensively considered, the fluid pressure is selected from four ranges a of 0.5MPa, 1.0MPa, 1.5MPa and 2.0Mp, and the influence of the fluid viscosity is larger, so that the selection range of the viscosity is 0.2-1000, and eight kinds of viscosities of 2.3, 23, 45, 72, 65, 125, 180 and 200 are selected. The empirical formula of the rotation coefficient of the spinning disk is as follows:
Figure BDA0002724279030000061
wherein S isδIs a rotation coefficient of, inbosIs the height of the column-shaped boss，HzFor the horn-shaped through cavity depth of the atomizing plate HjIs the depth of the annular rotational flow cavity sheet rbosIs the radius of the boss section, RcavIs the radius of the cylindrical groove, benWidth of liquid inlet channel, /)enIs the length of the liquid inlet channel.
In order to obtain enough sample points, the above variables are subjected to full experimental design, and the rotational speed set values of 160 spinning disks are totally obtained. In order to evaluate the prediction effect of the model, the samples are usually divided into two parts, namely training samples and prediction samples during training, and in view of the fact that the number of the samples is usually selected by a trial and error method at present, 120 groups of simulation data are randomly selected as the training samples and 40 groups of simulation data are randomly selected as the prediction samples according to experience.
And step two, carrying out BP neural network training.
In view of the fact that the BP neural network model researched by the invention aims at realizing the predictive control of the rotating speed of the spinning disk, in the model training process, the determination of the number of network layers and the number of neurons in each layer has great influence on the training effect, and the existing research results show that: the number of hidden layer neurons and the number of network layers supplement each other, that is, sufficient number of neurons can ensure that a three-layer forward network with only one hidden layer has a good approximation effect on a continuous function in a closed interval, and because an error transfer link is in direct proportion to the number of network layers, the generalization performance of the three-layer forward network is easily reduced by adopting a multi-layer neural network model, so that a three-layer BP network structure is selected, the number of neurons in an input layer is 3, the number of neurons in an output layer is 1, the number of hidden layers is 10, and the final parameter setting is shown in Table 1:

Because equivalent substitution is carried out on the rotating speed of the rotating flow sheet in the neural network model, rotating speed conversion is added in the prediction model, and therefore effective output of the opening degree of the grating is achieved.
The diffusion angle of atomizing nozzle diffusion length and atomizing nozzle is surveyed by outer characteristic time, and wherein, the nozzle atomizing diffusion length is shown as table 2 with the corresponding calculated result of spinning disk rotational speed:
TABLE 2 corresponding calculation result table of nozzle atomization diffusion length and spinning speed of spinning disk

Figure BDA0002724279030000081
Wherein, the nozzle atomizing diffusion angle and the corresponding calculated result of spinning disk rotational speed are shown in table 3:
TABLE 3 corresponding calculation result table of nozzle atomization diffusion angle and rotational speed of spinning disk
Figure BDA0002724279030000082
In order to verify the accuracy of the prediction model, four rotation speed models are selected for comparison experiments, and the calculated values are compared with the experiment results and the errors of the experiment results and analyzed, as shown in table 4, the calculated values of the four models are closer to the experiment values.
TABLE 4 error analysis Table
Figure BDA0002724279030000091
The absolute value of the maximum error is 5.3 percent and still in the range of the engineering allowable error, so that the calculation model meets the precision requirement.
