摘要

In this paper, a four-nozzle liquid oxygen (LOX)/kerosene rocket is used to analyse the afterburning effects on the thermal environment of flame deflectors. Based on the three-dimensional compressible Reynolds-Averaged Navier-Stokes (RANS) equations and the realizable k-ε turbulence model, the rocket plume model is established. A 9-species,10-steps chemistry scheme is used for the simulation of af...
