  • Abstract
    Turbulent air flow analysis is carried out in an ultra-thin hard disk drive using the large eddy simulation (LES). Aerodynamic force acting on various structural components is obtained for about 40 ms and analyzed in detail. Using one set of full scale simulation data, aerodynamic force data for other different sets of operating conditions is obtained using scaling methods thus minimizing the computational time significantly. Validation of the scaling methods is discussed and concluded.
