Abstract
The present paper describes a numerical procedure and its capability for calculating the film cooling effectiveness by injection from a single transverse row of discrete holes over a flat surface. The three-dimensional calculation procedure takes into account the elliptic nature of the flow after the injection. The effects of turbulence are simulated through the implementation of the standard k-ε turbulence model. Results are given for; two injection angles of 35° and 90o, spacing between the holes of 3 hole diameters, coolant-to-mainstream density ratios of 1.0 and 2.0, and blowing rates from 0.5-2.0. The predicted cooling effectiveness is compared with some available experimental data and shows an overall performance of reasonably good agreement.
