... experimental data, the numerical accuracy of VLES method was validated. With the VLES method, the unsteady heat transfer coefficient distributions on the squealer tip and total pressure loss in the blade passage were computed. The influences of coherent vortex structures on aero-thermal performance...

... and magnitude of the jet compares better. The unsteady case has slightly less low momentum fluid entrained into the jet and also a thinner boundary layer on both sides of the jet. This suggests that the entrainment is affected by the unsteadyness. k takes the value of 0.48, which is better than...
