자동차용 냉각수펌프의 설계전산화를 위한 특성해석

The purpose of this research was the basic study on performance of automotive water pump and throught it's characteristic analysis we will obtain optimum design value and also we will make Computer Aid Design program. It treated how to decide form of water pump from operation condition and performance of engine. We made an experiment through complement for performance test device of water pump for automotive engine in current use. It is difficult to expect high efficiency when we design it in the automotive water pump because we regulate loss caused by optimum design and constitutional limitation and character of water pump. Besides the number of impeller and it's size compare with water pump size are relatively large. As a result in this test we know that the efficiency of automotive water pump is 45%.
