Abstract

Based on the N-S equation, k-ε turbulence models and no-premixed combustion simplified PDF models, numerical studies on the mixing and combustion of fuel-gas and air in the afterburning chamber of solid rocket ramjet were carried out fewer than three special fuel-gas jets structures. The effects of the three special fuel-gas jets were analyzed and compared with simulation results of standard fuel-gas jets. The results show that, the mixing efficiency, full combustion extent and characteristic velocity in the afterburning chamber of solid rocket ramjet promoted when using special fuel-gas jets; mixing and combustion effects of 2# and 3# special fuel-gas jets better than that of 1# special fuel-gas jet, but they would bring more total pressure loss.

Key words： solid rocket ramjet; afterburning chamber; mixing and combustion; special fuel-gas jet; characteristic velocity
