Numerical Simulation and Experimental Validation of Temperature Field of Tank Power Train Compartment Body
|
Abstract:
A numerical analysis model for calculating the temperature field of a tank power train com- partment is established.A liquid-solid coupling calculating method is used to calculate the temperature field of the tank wall suface and a wall function method is used to modify the internal flow field of the solid wall.Through heat exchange calculation of solid-liquid two-way coupling and consideration of the effect of sun irradiation on body temperature field,the temperature field distribution on the wall surface of the tank body is derived.The calculation result is compared with the measurement result.The research result shows that the relative error between the calculation result and the measurement result is less than 9.034%.This numerical calculation method can be used to calculate and analyze the temperature field of the power train compartment body and can meet the needs of engineering applications basically.
