RISNote on Turbulent Kinetic Energy Production for Reynolds Averaged Navier–Stokes Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Linear eddyviscosity ReynoldsAveraged Navier–Stokes (RANS) turbulence models are based on the Boussinesq approximation that asserts the Reynolds stresses to be linearly dependent on the mean strain rate. Using the ...
Hybrid RANS/LES Simulation of Corner Stall in a Linear Compressor Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current design-cycle Reynolds-averaged Navier–Stokes (RANS) based computational fluid dynamics (CFD) methods have the tendency to over-predict corner-stall events for axial-flow compressors operating at off-design conditions. ...
Prediction of Transition and Losses in Compressor Cascades Using Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the 1950s, NACA conducted a series of lowspeed cascade experiments investigating the performance of NACA 65series compressor cascades with tests covering multiple airfoils of varying camber and with variations in solidity ...
