Impingement Heat Transfer In The Leading Edge Cavity Of A Gas Turbine Vane, Amar Jeetendra Panchangam Nivarthi

LSU Master's Theses

Jet Impingement Cooling is an internal cooling technique used in the leading edge cavities of Turbine Vanes. This involves a series of jets impinging onto the internal surfaces of a turbine vane/blade through the impingement plate. For the model tested here, the area around the blade/vane leading edge was studied for both heat transfer performance and aerodynamics losses. The performance of an Impingement cooling system depends on parameters like the spent flow effect on the downstream jet, film cooling configuration, and tip flow condition. The present study focuses on analyzing the effect of these parameters on a unique impingement cooling …
