Dissipation in Skewed Boundary Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The entropy generation within a turbulent, collateral boundary layer is well understood and is characterized by a dissipation coefficient, Cd. However, it is common for the transverse pressure gradients in turbomachines ...
A Framework for Estimating Effects of Combustor Turbulence on Turbine Profile Loss Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a framework to quantify the effect of freestream turbulence, generated by mixing processes in a combustor, on turbulent boundary layer loss generation in the high-pressure turbine downstream of the ...
Multifidelity Optimization of Turbulence in a Gas Turbine Combustor Simulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Combustor turbulence in a gas turbine engine greatly influences the efficiency of the downstream high-pressure turbine stage. Here we use a multifidelity computational optimization methodology to modify the geometry of a ...
The Impact of Combustor Turbulence on Turbine Loss Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A blade row that is located downstream of a combustor has an extremely high turbulence intensity at the inlet, typically above 10%. The peak turbulent length scale is also high, at around 20% of the chord of the downstream ...
