Simulation of the High-Pressure Combustion Process in Diesel Engines

High Pressure Flames with Multicomponent Transport

“…where m denotes the mean molecular weight of the mixture. Using these transport coefficients (20) and the diffusion driving forces (17), the multicomponent fluxes (13) (14) are rewritten in the more traditional form [32,34,35,37,52]…”

“…Supercritical cryogenic combustion is often encountered in rocket engines. This has motivated modeling and numerical simulation of supercritical mixing and combustion in laminar flows [1,2,3,4,5,6,7,8,9] and turbulent flows [10,11,12,13,14,15,16,17] as well as model rocket combustor experiments [18,19,20,21]. At such high-pressure and low temperature conditions, however, multicomponent transport phenomena is highly complex and nonidealities may influence the structure and dynamics of mixing zones as well as flames.…”
