| Abstract |
In HDD air flow simulation, the well known LES turbulent model requires large
computing times and resources, including CPU, RAM and storage intensive which is not
appropriate when using various variables. The effect of an air damper is studied by the k-e model
with a reduced boundary due to the lower number of equations, computing time and computer
resources. Firstly the RMS velocities of a partial model are compared between LES and k-e and
then the reduced boundary models are compared with the partial model. The RMS velocity errors of
the partial model compared with LES and k-e are less than 6 %. The mean RMS velocity errors
compared with the reduced boundary model and the partial model are 3.93% at ID and 2.12% at
MD position while the OD position increased to 26.5% because there is no effect from a return flow
from the flex bracket and voice coil zone. Computing time of the reduced boundary and k-e model
is reduced by 68.4%. In primary HDD air flow analysis, the k-e method together with a reduced
model can be used to predict the effect of an air damper. |
