The thermal effect of cool jets issuing into an incompressible hot cross flow at an angle over a turbine blade is the subject. Numerical solutions for twelve multiple flow arrangements with two flow ratios, two different hole spacing and four different jet issuing angles document strong to moderate secondary vortex structures spanning normal to the direction of the jet. This fully three-dimensi...
