S. Thakur et al., CONVECTION TREATMENT AND PRESSURE SPLITTING FOR SEQUENTIAL SOLUTION PROCEDURES .2. PRESSURE-BASED ALGORITHM, Numerical heat transfer. Part B, Fundamentals, 29(1), 1996, pp. 29-42
In Part II of the present article, the controlled variation scheme (CV
S) developed in Part I, and the advection upstream splitting method (A
USM) are implemented in a pressure-based algorithm, whose very basis i
s the separate treatment of convective and pressure fluxes For the con
vective fluxes in the momentum equations as well as the estimation of
mass fluxes in the pressure correction equation (which is derived from
tire momentum and continuity equations) of the present algorithm, bot
h first- and second-order (with minmod limiter) flux estimations are e
mployed. Some issues resulting from the conventional use in pressure-b
ased methods of a staggered grid, for the location of velocity compone
nts and pressure, are also addressed. Using the second-order fluxes, b
oth CVS- and AUSM-type schemes exhibit sharp resolution. Overall, the
combination of upwinding and splitting for the convective and pressure
fluxes separately exhibits robust performance for a variety of flows
and is particularly amenable for adoption in pressure-based methods.
