T1 Development of a Model for Turbulent Combustion within Porous Inert Media JF International Journal of Fluid Mechanics Research JO FMR YR 1998 FD 1998-06-01 VO 25 IS 1-3 SP 111 OP 122 AB Prior models for porous inert medium (PIM) burners have not been able to accurately predict burning speeds, CO emissions, and NOx emissions. All prior models for these burners have assumed laminar flow within the porous structure. However, there are reasons to believe that the flow within these burners is turbulent. Therefore, a turbulent PIM burner model has been developed. A one-equation k-ε. model is used to simulate the turbulent flow field. This model makes use of the fact that the pore size constrains the size of the largest turbulent eddies. Thus, the integral length scale, which is assumed to be a simple function of the pore size, is used to determine e. It is also assumed that the dominant effect of turbulence is enhancement of the transport properties. The increased transport properties result in broader flame zones, decreased gas temperatures, and increased burning rates. The decreased gas temperature results in decreased NOx emissions. The resulting predictions of the CO emissions are also improved. PB Begell House LK https://www.dl.begellhouse.com/journals/71cb29ca5b40f8f8,6b7c8043191c60e1,0350ed8b24c3dbda.html
