Effect of spatial differencing schemes on the performance of MOL solution of DOM in anisotropically scattering medium
Аннотация
Effects of spatial differencing practices on the predictive accuracy and computational efficiency of method of
lines solution of discrete ordinates method were investigated on a 1-D test problem with anisotropically
scattering medium by utilizing two-, three-, four-point upwind and four-, five-point biased upwind schemes and
comparing predicted radiative heat fluxes with exact solutions available in the literature. Comparisons show that
five-point biased upwind scheme produces accurate solutions in much less CPU time than the others and that
four-point upwind scheme leads to instability.
