Property flowing in, turn the difference of enthalpy on same streamline between 2 points, represent the flow losses in process fluid flow.Fig. 6 a are same
Turn enthalpy change curve on streamline.As seen from the figure, original conventional fluid torque-converter to turn enthalpy anxious at dimensionless distance " 0.2 " place
Play declines, and is tended to be steady after reaching dimensionless distance " 0.5 " place.Illustrate original conventional fluid torque-converter in blade maximum curvature section
Fluid flow losses are huge, and the fluid torque-converter designed by the utility model embodiment 1 then turns at dimensionless distance " 0.4 " place
Enthalpy just starts to be gradually reduced, and at entrance blade section processing obvious flow losses just occur for this explanation flow liquid.Separately
Outside, the enthalpy that turns of original conventional fluid torque-converter changes apparently higher than the fluid torque-converter designed by the utility model embodiment 1
What is obtained turns enthalpy change value, that is to say, that the fluid torque-converter fluid flow loss designed by the utility model embodiment 1 is smaller.

Significantly big ups and downs are given birth to, and the two change shape is substantially similar.Fluid power designed by the utility model embodiment 1 becomes
Square device drastically raises at dimensionless distance " 0.4 " both places, reaches gradually descending behind peak, becomes at dimensionless distance " 0.6 " place
In normal level, that is this is handled according to the fluid torque-converter section designed by the utility model embodiment 1 after, in master
Vane recesses section, tubulence energy sharply increase, i.e., have very powerful eddying motion in this stage, turbulence dissipation rate is in the form of same
Fluctuation, illustrates that this powerful turbulent eddy yardstick is small, and evolution is formed and disappearance is exceedingly fast, and in this powerful turbulent flow whirlpool
Volute into when, the pressure of wall can be increased.
Original conventional fluid torque-converter is compared, the performance of the fluid torque-converter designed by the utility model embodiment 1 has
Considerable raising, maximal efficiency bring up to 87.16% from 86.2%, and stall torque ratio brings up to 2.63, while stall work by 2.454
