AI Technical Summary
Existing technology cannot accurately calculate the temperature distribution in different parts of the engine compartment, resulting in inaccurate assessment of heat hazard points in critical components, which affects engine efficiency and lifespan.
By constructing a geometric simulation model and a physical model of the engine, the heat source value of the radiator volume, the fan speed and the resistance parameters are calculated. Combined with the boundary conditions of the flow field domain, the Navier-Stokes equations are used to calculate the temperature distribution in the gas domain and the solid domain.
It enables accurate calculation of temperature distribution in various parts of the engine compartment, accurately assesses the location of heat hazard points in important components, and improves the accuracy of engine performance evaluation.
