... are experimentally investigated. The channel is oriented 120 deg with respect to the direction of rotation to model the geometry of an internal, trailing-edge cooling passage. Both the leading and trailing sides of the channel are divided into three and six regions in the spanwise and streamwise directions...

... and spanwise directions are experimentally investigated. To model the geometry of an internal trailing edge cooling passage, the channel is oriented with respect to the direction of rotation (β = 120 deg). Isolated copper plates are used to obtain regionally averaged heat transfer coefficients on the leading...

... thermography trailing edge The continuous demand of high thermal efficiency and power output for propulsive and land-based gas turbines has led the turbine inlet temperature to increase up to nearly 1900 °C. To mitigate the demand of such a high temperature, more efficient cooling techniques...

...Marcel Otto; Gaurav Gupta; Patrick K. Tran; Shinjan Ghosh; Jayanta S. Kapat Arrays of staggered pin fins are a typical geometry found in the trailing edge region of modern airfoils. If coolant is supplied by bleeding from the mid-section of the airfoil instead of provided through the root...

..., 2013. Assoc. Editor: Karen A. Thole. 08 12 2010 05 01 2012 The present experimental study is to examine the influence of trailing-edge coolant ejection with the span-wise inclination on the aerodynamic loss of turbine nozzle guide vanes. This study uses a cascade of five vanes...
