Viscous multiblock simulations of axisymmetric launch vehicle flows
TLDR
Axisymmetric, turbulent, viscous flow simulations over the first Brazilian satellite launcher are presented and the increased resolution of the multiblock calculations for the afterbody region is evidenced through comparisons with previous single-block grid solutions.
