Abstract

Low aspect ratio pin fins are used to improve the heat transfer in turbine blades. The present study compares experimental pressure drop measurements for several pin fins arrays with DNS results. For arrays greater than 6 rows the friction factor becomes independent of the number of rows. DNS shows that this is due to the form drag accounting for approximately the 90% of the total drag.
