Navier-Stokes simulations of rotor-stator interaction using patched and overlaid grids

Three-dimensional Navier-Stokes simulation of Space Shuttle Main Propulsion 17-inch disconnect valves

“…In the absence of relaxation, the maximum CFL number for a given grid is reduced and depends, in general, on the number of spatial dimensions of the ADI scheme, the complexity of the geometry, and Reynolds number. For example, Rai 34 reported values of CFL = 250 in a two-dimensional Navier-Stokes simulation of rotor/stator interaction. Values of CFL > 500 produced unstable results.…”

Towards Rocket Engine Components with Increased Strength and Robust Operating Characteristics

“…The algebraically-generated Hgrids are used to discretize the remainder of the flow field. Details of the algorithms and the gridding methodology can be found in references [14,15 and IS].…”

Unsteady Aerodynamics & Aeormechanics of Multi-Stage Turbomachinery Blading

“…This approach was iitiplemented by Giles [17] (two-dimensional Euler equations), Rai [50] (two-dimensional Navier-Stokes equations), Giles and Saxer [54] (three-dimensional Euler equations), aod Rai [51,52] (three-dimensional NavierStokes equations). In these methods, separate grids are generated for the stator and for the rotor with a common interface between the blade rows.…”
