Summary :

ABSTRACT. A UNIFIED FORMULATION FOR BOTH COMPRESSIBLE AND NEARLY INCOMPRESSIBLE VISCOUS FLOW IS PRESENTED. THE NEW METHOD IS A SUBTLE BUT RELEVANT MODIFICATION TO THE AUTHORS?PREVIOUS FORMULATION FOR ALL SPEED FLOW. THE NEW DISCRETISED EQUATIONS ASSUME A SIMPLER FORM, LEADING TO AN EASIER AND MORE EFFICIENT COMPUTER IMPLEMENTATION. THE MAIN FEATURES REMAIN THE SAME: THE USE OF A SEGREGATED SCHEME, THE CHOICE OF MASS-VELOCITY (DENSITY*VELOCITY), INTERNAL ENERGY AND PRESSURE AS DEPENDENT VARIABLES, AND THE INTRODUCTION OF A STRONGLY IMPLICIT PRESSURE EQUATION. THE METHOD IS APPLIED TO THE ANALYSIS OF LAMINAR FLOWS GOVERNED BY THE NAVIER-STOKES EQUATIONS. COMPUTATIONS OF TRANSONIC AND SUPERSONIC VISCOUS FLOWS AROUND A NACA0012 AIRFOIL ARE PRESENTED.
KEYWORDS: COMPUTATIONAL FLUID DYNAMICS, AERODYNAMICS, ADAPTIVE METHODS.
