Computation of Off-Design Flows in a Transonic Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent years have seen increasing efforts to develop efficient solvers for the compressible Navier–Stokes equations. For maximum benefit to be derived from this effort, these Navier–Stokes solvers ...
On the Interpretation of Measured Profile Losses in Unsteady Wake–Turbine Blade Interaction Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The interaction of wakes shed by a moving blade row with a downstream blade row causes unsteady flow. The meaning of the free-stream stagnation pressure and stagnation enthalpy in these ...
The Extension and Application of Three-Dimensional Time-Marching Analyses to Incompressible Turbomachinery Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional time-marching flow solvers perform poorly when integrating compressible flow equations at low Mach number levels. This is shown to be due to unfavorable interaction between long-wavelength ...
