Numerical simulation of a flat plate film cooling with a coolant supply into different shape indentations

Numerical simulation of a flat plate film cooling with a coolant supply into different shape... Abstract Results of a film cooling numerical simulation over a flat plate with coolant supply into indentations of different shape are reported. The calculations were performed for the blowing-ratio changed from 0.5 to 2.0. For comparison, data for traditional film cooling scheme with one row of discrete cylindrical inclined holes were used. At small value of blowing ratio (m = 0.5), the average film-cooling efficiency is roughly identical for all indentations tested. With blowing ratio growth, the scheme with a coolant supply into the transverse trench demonstrates the best results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Results of a film cooling numerical simulation over a flat plate with coolant supply into indentations of different shape are reported. The calculations were performed for the blowing-ratio changed from 0.5 to 2.0. For comparison, data for traditional film cooling scheme with one row of discrete cylindrical inclined holes were used. At small value of blowing ratio (m = 0.5), the average film-cooling efficiency is roughly identical for all indentations tested. With blowing ratio growth, the scheme with a coolant supply into the transverse trench demonstrates the best results.
