Fabrication and Testing of a Heat Exchanger Module for Thermoelectric Power Generation in an Automobile Exhaust System
(Virginia Tech, 2013-01-07)
Thermoelectric generators (TEGs) are currently a topic of interest in the field of energy harvesting for automobiles. In applying TEGs to the outside of the exhaust tailpipe of a vehicle, the difference in temperature ...
Heat Transfer Measurements Using Thin Film Gauges and Infrared Thermography on a Film Cooled Transonic Vane
(Virginia Tech, 2009-05-04)
This work presents a comparison of thin film gauge (TFG) and infrared (IR) thermography measurement techniques to simultaneously determine heat transfer coefficient and film cooling effectiveness. The first comparison was ...
3D Numerical Simulation to Determine Liner Wall Heat Transfer and Flow through a Radial Swirler of an Annular Turbine Combustor
(Virginia Tech, 2013-08-26)
RANS models in CFD are used to predict the liner wall heat transfer characteristics of a gas turbine annular combustor with radial swirlers, over a Reynolds number range from 50,000 to 840,000. A three dimensional hybrid ...
Effect of Blowing Ratio on the Nusselt Number and Film Cooling Effectiveness Distributions of a Showerhead Film Cooled Blade in a Transonic Cascade
(Virginia Tech, 2007-07-16)
This paper investigates the effect of blowing ratio on the film cooling performance of a showerhead film cooled first stage turbine blade. The blade was instrumented with double-sided thin film heat flux gages to ...
Heat Transfer Performance Improvement Technologies for Hot Gas Path Components in Gas Turbines
(Virginia Tech, 2016-06-14)
In the past few decades, the operating temperatures of gas turbine engines have increased significantly with a view towards increasing the overall thermal efficiency and specific power output. As a result of increased ...
