자동차 프런트 앤드 쿨링팬 개발

초록

A automobile front-end cooling fan are designed and tested in the present study. The design technique is developed using the one-dimentional inviscid flow through the fan blade, the empirical equation, and the performance prediction models. Numerical calculations of the three-dimentional turbilent flow around the designed cooling fan are carried out. Flow characteristics and pressure distributions on the pressure and suction side of the fan are investigated. Performance test results of the total pressure and flow rate are presented.
