摘要
在乙二醇冷却液中添加Cu纳米粒子作为内燃机冷却介质,并利用大型CFD软件AVLFire针对两种不同的冷却介质对内燃机冷却系统的传热进行了三维模拟计算。通过计算可以得到传热工质的流场、压力场及壁面换热系数的空间分布。结果表明,以Cu-乙二醇纳米流体作为传热工质可以提高内燃机的散热性能,而且水套进出口压降有所降低。
The glycol coolant added Cu nano-particles was used as the internal combustion engine coolant,and the commercial CFD software AVL Fire was employed to perform the 3D numerical simulation of the cooling system of engine with different coolant.The flow field,the pressure field and the surface heat transfer coefficient distribution were obtained by the simulation.The results indicate that nano-fluids can evidently enhance the engine heat transfer capability,and reduce pressure loss.
