...Sean C. Jenkins; David G. Bogard The turbine section of a gas turbine engine is subjected to hot gases flowing from the combustor that typically have high temperature regions known as “hot streaks.” These hot streaks pass through the nozzle guide vanes, either impacting the vanes or passing through...

...Bai-Tao An; Jian-Jun Liu; Hong-De Jiang This paper presents a detailed flow and heat transfer characteristic analysis on gas turbine first-stage turbine under hot streak inlet conditions. Two kinds of inlet total temperature conditions are specified at the turbine stage inlet. The first is uniform...

...Sean C. Jenkins; David G. Bogard The turbine section of a gas turbine engine is subjected to a nonuniform temperature distribution in the gas flow from the combustor. Regions of elevated temperatures, known as “hot streaks,” subject the turbine airfoil to high heat loads. In this study...
