因某公司车用冷却水泵工作效率低下,故对该水泵进行流场分析。将水泵的内部流场模型导入Fluent中进行计算分析,得到水泵流场的速度、压力及湍动能分布图。分析结果发现该水泵存在压力、湍动能分布不均,易发生汽蚀和能量消耗,故对该水泵模型结构优化后再对新、旧水泵的分析结果进行比较和计算,发现优化后的水泵工作效率得到提高。 Due to a company car cooling water pump low efficiency, so the pump flow field analysis. The internal flow field model of the pump is introduced into Fluent for calculation and analysis, and the velocity, pressure and turbulent kinetic energy distribution of the pump flow field are obtained. The analysis shows that the pump has pressure and turbulent kinetic energy distributed unevenly, cavitation and energy consumption are easy to occur. Therefore, after the pump model structure is optimized, the analysis results of new and old pumps are compared and calculated, and the optimized pump work Efficiency is improved.
