SHIEH; C. SHIEH. An implicit three-dimensional Navier-Stokes solver for compressible flow. 3-D Navier-Stokes simulation of turbulent afterbody/nozzle flows. Three dimensional transonic viscous flow computations are presented for a generic high-speed accelerator model which includes wing, body, filets,and a no-flow through engine nacelle.
solutions are obtained from an algorithm for the compressible Navier-Stokes equations which incorporated an upwind-biased, flux-vector-splitting approach along with longitudinally-patched grids. The flow over afterbody geometries was investigated using the reduced Navier-Stokes (RNS) approximation.
Both pressure velocity flux-split and composites velocity primitive variable formulations were considered. Pressure or pseudopotential relaxation procedures are combined with sparse matrix or coupled strongly implicit algorithms to form a three-dimensional solver for general non-orthogonal.

The solution of the resulting Navier-Stokes equations presents a formidable problem, especially when the Reynolds number is high so that the length scales relevant to the parabolic terms and to the convective terms become widely disparate.

Computed solutions of the time-dependent, Reynolds-averaged Navier-Stokes equations for three-dimensional flows having thin shear layers are analyzed, using topological concepts. Specific examples include the transonic flow over a body of revolution with conical afterbody at moderate angles of incidence to the free stream.
starting solution over the afterbody based on the forebody solution. The forebody flowfield can then be used as a boundary condition and the thin-shear-layer Navier-Stokes solution advanced in time to a steady state in the afterbody region only. This is the procedure adopted in the present study.
The parabolized Navier-Stokes solutions are obtained. For transonic flow cases, the Enquist-Osher flux biasing scheme developed for the full potential equation is used.
A quasi-conservation form of the governing equations is used in the shock region to capture the correct rotational behavior. The composite velocity procedure is applied for the solution of three-dimensional afterbody problems. Two- and three-dimensional, steady and unsteady viscous flow fields are numerically simulated by solving the Navier-Stokes equations.
A solution-adaptive-grid method is used to redistribute the grid points so as to improve the resolution of shock waves and shear layers without increasing the number of grid points. Flow fields considered include two-dimensional transonic flows about airfoils.
Buffeting flow on transonic aerofoils serves as a model problem for the more complex three-dimensional flows responsible for aeroplane buffet.
The origins of transonic aerofoil buffet are linked to a global instability, which leads to shock oscillations and dramatic lift fluctuations.

Leicher, S. Analysis of Transonic and Supersonic Flows Around Wing-Body Combinations, ICAS 84–1. In this study, several questions relevant to the viscous transonic cascade problem are posed and answered by considering simple flow situations.
These questions focus upon spatial differencing, specification of boundary conditions and use of artificial dissipation in flows containing shock waves. In regard to the first of these problems, the model problem clearly shows that converged solutions.
