F. Grasso et M. Marini, SOLUTIONS OF HYPERSONIC VISCOUS FLOWS WITH TOTAL VARIATION DIMINISHING MULTIGRID TECHNIQUES, Computers & fluids, 24(5), 1995, pp. 571-592
In the present paper a multigrid technique based on the Full Approxima
tion Storage Full Multigrid method with ''V-cycle'' strategy and direc
tional grid transfer operators has been developed for hypersonic visco
us hows. A truly two-dimensional stability analysis of the strategy ha
s been developed to assess the damping properties and the influence of
grid transfer operators. The full Navier-Stokes equations are solved
by a finite volume approach based on a total variation diminishing dis
cretization and explicit Runge-Kutta algorithm. The technique has been
applied to compute simple and complex hypersonic hows, showing that f
aster convergence is achieved by means of upwind prolongation operator
s. However, for supersonic hows the technique shows no advantage over
the standard approach.
