A study on cooling of multi-disc flow paths with swirl velocity component

Abstract

It is important to know the flow of the cooling fluid inside the product. In the case of a motor, in order to make compact and lightweight, efficient cooling of the motor must be performed. However, it is difficult to see the flow. In this study, in-house code written by fortran language is used to visualize the flow in the motor. At that time, simulation of cooling was performed under the condition that the same rotation as the actual operating situation was added, and how each core was cooled was investigated. As a result, it was found that each core was not evenly cooled.
