Numerical evaluation of heat/mass transfer analogy for leading edge showerhead film cooling on a first-stage vane

Mesh sensitivity of RANS simulations on film cooling flow

“…The study indicated that surface curvature and rotation significantly affected the film cooling effectiveness and jet interactions. Ravelli and Barigozzi [26] utilised the heat/mass transfer analogy in an investigation on leading-edge film cooling on a first-stage vane. The Realizable k − ε turbulence model with enhanced wall treatment was used as the turbulence closure.…”
