G7 동력차 동력실 유동해석을 통한 루프후드 구조 연구

The study for roof hood structure of G7 power car engine compartment using air flow analysis.

The study was carried out about the roof hood structure of power car for Korean High Speed Train. The compatibility for applied material and volume of hood duct was studied using analysis about heat and flow distributions. The materials and volume of duct were mainly determined by output air temperature and flow rate of each electric blocks. This report was described, which focuses on pressure distribution and air temperature within engine compartment of power car.
