...H. Ma; Q. Zhang; L. He; Z. Wang; L. Wang A basic attribute for turbine blade film cooling is that coolant injected should be largely passively convected by the local base flow. However, the effective working of the conventional wisdom may be compromised when the cooling injection strongly interacts...
