CFX를 이용한 내부순환모드에서의 자동차 내부 유동특성 연구

다국어 초록 (Multilingual Abstract)

The flow characteristics under recirculation cool vent mode is numerically studied using commercial fluid dynamic cade(CFX). For the reliable analysis, real vehicle and human FE model is employed in grid generation process. The geometrical location and shape of panel vent, and exhaust vent is set as that of real vehicle model. The flowrate of the working fluid is determined as 330CMH which is equivalent to 70 percent of maximum capacity of HVAC system. The high velocity regions are formed around 4 each panel vent. Because of the non-symmetrically located exhaust, non-uniform flow and partial backflow near the door trim is observed. Streaklines start from each panel vent show the flow pattern of the airflow in the passenger's compartment very well.
