수치해석적 기법을 이용한 스탠드 김치냉장고용 냉각 원심팬의 최적 설계

In this study, the cooling centrifugal fan of vertical type Kimchi refrigerator is developed from using computational fluid dynamics(CFD) and design of experiment(DOE) to overcome performance loss caused by restricted structure. In order to improve fan performance, essential variable of centrifugal fan is optimized using response surface method(RSM). To verify optimized result from response surface method(RSM), we actually make a cooling fan applied optimized and performed flow rate experiment.
