Abstract

The purpose of this research is to investigate the ventilation system within HDD manufacturing using a numerical simulation (computational fluid dynamics or CFD) in order to study the effect of the temperature and relative humidity distribution. The results from this research are reported in term of thermal comfort. The study focuses on the HDD testing area and boundary conditions are obtained through temperature and relative humidity measurements in the area, which is located in the HDD tester at the manufacture on a typical day. The distribution in temperature and relative humidity were analyze by the MATLAB® to determine the thermal boundary. The results of this study showed that the distribution of temperature and relative humidity are not good enough due to the air supply location in HDD tester area cannot afford the effective air distribution into the HDD testing area. It was found that the air distribution can be improved by using simulation results.
