Baer, M R

A computational procedure is employed to determine the axisymmetric reactive flow field within a cylindrical combustor. The full 2-D elliptic partial differential equations are solved and a second order closure method is used for the turbulence modeling. Turbulent combustion is represented with the aid of Spalding's eddy-breakup model. These flow-field predictions are compared with the experimental measurements obtained by Cooper, Marek, and Strehlow and show very good agreement on the distribution of the species throughout the flow. The lateral momentum effect of swirl has been introduced; however flow prediction remains unverified. This research is directed at identifying proper entrance conditions to an MHD channel from a pulverized coal combustor.
