摘要
本文基于有限体积法软件,以某柴油发动机所用机油泵为研究对象,使用UDF函数和动网格,湍流模型选取RNGκ-ε模型,对机油泵的内部流场进行瞬态数值模拟。结果表明:使用有限体积法软件对机油泵进行瞬态数值模拟,能够客观的反映机油泵内部流场的压力,速度,流量等特性,验证了CFD数值模拟方法对摆线泵进行研究的可行性。
Based on finite volume method, this paper analyzes the transient performance of oil pump of disel engine. Choose RNG K-e model, with the method of UDF function and dynamic mesh. The result shows that the simulation of the transient performance of oil pump can reflect the interior fluid performance, such as pressure, velocity and flow rate,and CFD numerical simulation of oil pump is feasible.
