Vane Film-Cooling and Heat Transfer |
|
Siemens is currently sponsoring a project investigating the film-cooling for a nozzle guide vane of an industrial gas turbine similar to the one shown in Figure 1. This project involves both computational and experimental fluid dynamics to quantify the heat transfer and adiabatic wall temperatures on the turbine vane surface. FLUENT and TEXSTAN are being used to make predictions about the flow and thermal fields around the vane surface (Figure 2). Experimental validation is being completed in a large-scale low-speed wind tunnel facility at PSU ExCCL. Specific aspects of this project that are new and interesting include the following: surface heat transfer measurements on the turbine vane in the presence of a contoured endwall (experimental setup shown in Figure 3) and adiabatic surface temperature measurements on a fully-cooled turbine vane with fan-shaped film-cooling. |
