Progress is described on a model of the turbulent axisymmetric base flow behind bluff-base bodies. The purpose of the model is to provide an analytical basis for incorporation of external burning and base injection effects upon the base flow. An integral technique is used for solution of the problem. At the current time , however , extreme difficulties are being encountered in the choi ce of field variable profiles to insert in the integral technique. Several choices of profiles and governing moment equations are yiel ding a singulari ty before the rear stagnation point is reached in a downstream, integration of the equation .
