Abstract

The present study aims at clarifying the turbulent structure developing in a hard disk drive through the measurement of fluctuating pressure on the shroud wall. The measurements have been conducted in two different models, with and without read-write arms, and the results are compared to characterize the effect of the internal structure of turbulent flow on the device. The effect of read-write arms is found to be of primary importance, as it changes the flow structure drastically, with the increasing the arm insertion angle. The most pronounced effect has been found in the gradual change of the characteristic frequency in the power spectrum density of the pressure fluctuation: Both qualitative and quantitative changes are observed.
