A NUMERICAL STUDY FOR IMPROVING PERFORMANCE ON PAINT DRYING SYSTEM OF A VEHICLE

차량 도장 건조 성능 향상을 위한 수치해석 연구

In the present study, a three-dimensional numerical simulation was performed in a paint drying system of vehicle assembly line. In the drying system hot air and cool air are blown in turn from the nozzles to dry the trim of vehicle. Inlet boundary condition using user subroutine code is adopted to consider the moving motion of the vehicle. The present paper aims to improve the performance of the drying system. The transient distribution of temperature and velocity at the surface of the vehicle were predicted numerically. From these results, optimal operating condition of the drying system are to be suggested.
