According to the design requirements of high-temperature combustion chamber. an advanced shaped hole structure was designed for film cooling. Numerical method was applied in this study to investigate the flow and heat transfer characteristics of shaped holes and compared with those of cylindrical holes. The influence of the forward expansion angle of shaped holes on the flow and heat ... https://www.spidertattooz.com/DND-500-600-Base-Top-Gel-Lacquer-Combo-Champagne-Sparkles-710-p35990/
