ABSTRACT
Turbulent combustion remains as a very diÆcult, and perhaps the most impor-
tant, problem in chemical propulsion [1, 2]. The challenges in establishing a
thorough understanding of this phenomenon have been well recognized [3]. De-
spite being the subject of widespread research, there are many physical issues
in enhancing our understanding of turbulent combustion that are yet to be re-
solved. These issues are not only associated with turbulence, but also include
other phenomena such as chemistry of combustion, multiphase transport, scalar
mixing, thermal radiation, compressibility, etc. [4]. All of these have been sub-
jects of research on their own merits; they are substantially more diÆcult when
considered in conjunction with turbulent transport.
