Area of Research: Aero/Heat Transfer

Federal Project Manager: Mark Freeman

Project Objective: The primary goal of this research project is to provide design data and tools to engineers by studying fluid-thermal particle dynamics of residual syngas ash in the leading edge region of a turbine blade in the presence of film-cooling jets and to quantify the potential deposition and erosion under different flow and thermal conditions. Objectives are to investigate deposition in a three-hole leading edge film-cooled geometry at different blowing ratios and particle sizes and to nvestigate the use of polymer materials as a substitute for coal ash for low-temperature experiments.
