An efficient numerical method for solving the time-dependent compressible Navier-Stokes equations at high Reynolds number
Author(s): Maccormack, R. W.
Abstract: A new numerical method used to drastically reduce the computation time required to solve the Navier-Stokes equations at flight Reynolds numbers is described. The new method makes it possible and practical to calculate many ...

Numerical solution of the time-dependent compressible Navier-Stokes equations in inlet regions
Author(s): Olson, L. E.; Mcgowan, P. R.; Maccormack, R. W.
Abstract: The results of a study to determine the effects of compressibility on the viscous flow through channels that have straight, parallel walls are presented. Two channel configurations are considered, the flow between two ...

On the validation of a code and a turbulence model appropriate to circulation control airfoils
Author(s): Viegas, J. R.; Rubesin, M. W.; Maccormack, R. W.
Abstract: A computer code for calculating flow about a circulation control airfoil within a wind tunnel test section has been developed. This code is being validated for eventual use as an aid to design such airfoils. The concept of ...

Transonic-flow computation using an explicit-implicit method
Author(s): Kordulla, W.; Maccormack, R. W.
Abstract: The explicit-implicit predictor corrector method of MacCormack (1981) is applied to the analysis of flows past airfoils. By comparing results obtained with different methods and meshes, it is shown that the above method ...
