Abstract: L25.00010 : On the Heat Flux Components in Supersonic Combustion of a Detonation Engine*
9:57 AM–10:10 AM
(Stony Brook University)
The maximum static pressure occurs at the transverse detonation wave, with a value that is one order of magnitude higher than the relatively uniform values that are found in most part of the domain. We were able to determine the axial distance at which most of the reactions have taken place, and we found that the formation convective heat flux has the largest contribution, followed very closely by its sensible counterpart, whose magnitude is roughly half of that for the formation enthalpy heat flux. The conductive heat flux has the smallest magnitude, which is roughly one order smaller than the mass diffusion values. The Nusselt number and heat transfer coefficient for the present problem are significantly higher than those encountered in low-speed, non-reacting flow fields.
