This study is an investigation into the effects of density ratio on the jet structure of different film cooling configurations. A simple-shaped cylindrical hole is tested at a tight spacing, which has a lateral and streamwise pitch-to-hole-diameter r

We present highly resolved large eddy simulation (LES) of a realistic effusion cooling geometry. The test case features mixing between a high-density working fluid (CO2) and a low-density crossflow (air) to mimic the density stratification in typical
