Abstract
This paper deals with the specific tools necessary to investigate airflow in HDD with the aerodynamic parts. The simulation modeling of HDD is made by using large eddy simulation (LES), which covers most of the configuration between the two co-rotating disks, including the arm assembly and effective methods for investigating the airflow inside an actual HDD, namely, particle image velocimetry (PIV) with tetrahedral elements.
