Film cooling analysis using LES turbulence model

Abstract

Film cooling is a process that is used to protect turbine vanes in a gas turbine engine from exposure to hot combustion gases. In this paper, we have conducted the time-dependent analysis of film cooling by the large-eddy-simulation (LES) model. We have obtained static-temperature contours, pressure contours, velocity vectors and temperature plot at y = 12.7 mm iso-surface at different time intervals such as 10, 20.37 and 40.74 s. Significant results have been obtained.
