원심형 제트송풍기의 노즐 형상 최적설계

초록

In the present work, shape of nozzle in a centrifugal jet fan is optimized numerically using three-dimensional Reynolds-averaged Navier-Stokes analysis, Standard k-e model is used as a turbulence closure. Response surface method is employed as an optimization technique. The objective function is defined as maximum throw and three design variables are defined as angle, length of nozzle exit and interval between tow nozzles.
