Abstract
The flow pattern of the hard disk drive is correlated with the spinning speed produced of the disk, while spinning speed is the factor affecting the performance of the drive. The aim of this study was to investigate the airflow inside the hard disk drive. The simulation model is constructed based on the currently available 2.5-inches disk drive in the market, with 5400 rpm disk rotation speed. ANSYS Fluent is applied to analyze the airflow characteristic. Good agreement in normalized velocity magnitude and vectors plot shows the flowing of the air surrounded the drive region. In conclusion, it is found out that the results have close agreement with each other, with a range of percentage differences and errors between 2% to 5%.
