Cooling hole geometry and turbulence effects on the early suction side surface of a turbine vane
Most film cooling research is conducted on simplified experiments such as low speed flat plates. The research is used to derive empirical correlations, later applied during the design phase of film cooling systems. This thesis looks at small design changes in the film cooling geometry on the early …

Aerodynamic performance measurements of a film-cooled turbine stage
… stage and to quantify the loss caused by film-cooling. A secondary goal of the research is to provide a detailed breakdown of the losses associated with film-cooling for the turbine stage being tested. The experimental work was carried out at the MIT Blowdown Turbine Facility using a highly …

Numerical investigation of the influence of elevated turbulence levels on the cooling effectiveness of an anti-vortex hole geometry
A novel film cooling hole geometry for use in gas turbine engines has been investigated numerically by solving the Reynolds Averaged Navier-Stokes equations in a commercial CFD code (STAR-CCM+) with varying turbulence intensity and length scale using the k-o SST turbulence model. Both steady and …

Analysis of film cooling performance of tripod hole
… load it can bear. This is where gas turbine cooling becomes very critical and a better cooling design has the potential to extend the blade life span, enables higher rotor inlet temperatures, conserves compressor bleed air. Among various kinds of cooling involved in gas turbines, film cooling …
