Simulation Analysis of New Energy Vehicle Engine Cooling System Based on K-E Turbulent Flow Mathematical Model

New energy vehicles have better clean and environmental protection characteristics than traditional fuel vehicles. The new engine cooling technology is critical in the design of This paper used one-and three-way joint simulation methods to simulate refrigeration system Firstly, a k-ε turbulent flow model for pump field established based on principle computational fluid dynamics. Then, CFD commercial analysis software FLUENT under different inlet conditions. proposes an optimization scheme vehicle engines’ “boiling” phenomenon high temperatures long-time climbing results show that changing radiator’s structure adjusting thermostat’s parameters can solve problem “boiling pot.” optimized maintain operating temperature range. algorithm reference each cryogenic component hardware selection control strategy vehicle’s engine.
