RISThe Influence of Leading Edge Diameter on Stagnation Region Heat Transfer Augmentation Including Effects of Turbulence Level, Scale, and Reynolds Number
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stagnation region heat transfer measurements have been acquired on two large cylindrical leading edge test surfaces having a four to one range in leading edge diameter. Heat transfer measurements have been acquired for six ...
Simulations of Slot Film-Cooling With Freestream Acceleration and Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slot film cooling in an accelerating boundary layer with high freestream turbulence is studied numerically using large eddy simulations (LES). Calculations are done for a symmetrical leading edge geometry with the slot fed ...
Large Eddy Simulation of the Laminar Heat Transfer Augmentation on the Pressure Side of a Turbine Vane Under Freestream Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vane pressure side heat transfer is studied numerically using large eddy simulation (LES) on an aft-loaded vane with a large leading edge over a range of turbulence conditions. Numerical simulations are performed in a ...
Large Eddy Simulation of Bypass Transition in Vane Passage With Freestream Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High Reynolds flow over a nozzle guide-vane with elevated inflow turbulence was simulated using wall-resolved large eddy simulation (LES). The simulations were undertaken at an exit Reynolds number of 0.5 × 106 and inflow ...
Local Cooling Enhancement in Incremental Impingement Pin-Fin Configurations: Role of Jet Diameter and Impingement Configurations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study numerically investigates low aspect ratio incremental impingement configurations to evaluate the effect of jet hole size on both local and global heat transfer. The large eddy simulation (LES) model is developed ...

The Influence of Turbulence and Reynolds Number on Endwall Heat Transfer in a Vane Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Endwall heat transfer measurements have been acquired in a vane cascade over a range of turbulence conditions and Reynolds numbers using an array of small commercial infrared (IR) cameras. The linear cascade was tested ...
Heat Transfer and Pressure Drop Measurements in High Solidity Pin Fin Cooling Arrays With Incremental Replenishment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leading edge heat loads on turbine airfoils can be reduced by increasing the diameter of the leading edge. The lower external heat transfer and more generous curvature may allow for cooling this region internally. Large ...
Vane Suction Surface Heat Transfer in Regions of Secondary Flows: The Influence of Turbulence Level, Reynolds Number, and the Endwall Boundary Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Secondary flows in vane passages sweep off the endwall and onto the suction surface at a location typically close to the throat. These endwall/vane junction flows often have an immediate impact on heat transfer in this ...
