Numerical simulation of multi-stream nozzle flows

Applied Computational Aerodynamics

“…When several grid levels are used, the distribution rule is applied once on each level down to the coarsest grid, and the corrections are then interpolated back to the fine grid. Distributed correction schemes of this type have been further developed by Hall, 65 with very good results. They have also been extended to the Navier-Stokes equations by Chima and Johnson.…”

“…Second, for effective application of the methods, it is necessary to possess a considerable understanding of functions of complex variables. 65 Even experts may find extension of existing techniques to differing configurations to be a formidable task.…”

“…65 ' 66 For many installations viscous effects can be ignored, and an exhaust simulation based on the potential or Euler formulation can be used. The potential-flow formulation is inherently limited to regions of a constant total temperature and pressure and at first glance does not seem well suited for modeling exhaust flows.…”
