| Abstract | 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 using the IC-E turbulence closure model for eight multiple hole arrangements with three different hole spacings and three different jet issuing angles document strong to moderate secondary vortex structures spanning normal to the direction of the jet. This fully three dimensional flow field strongly influences the cooling performance of the hole-blade system. For a generalized bodyfitted three dimensional finite element model, computational results suggest an optimum hole spacing and low issuing angle for maximum cooling efficiency. |
