Abstract : An interacting zone method of calculation is developed for predicting stalled turbulent flows which are nominally two-dimensional, incompressible, and steady. The total problem is divided into zones selected such that each can be represented by a manageable analytical model. When applied to the case of the fully stalled diffuser, adequate a priori predictions are achieved with careful handling. Predictions show a strong sensitivity to location of separation -- as does the actual diffuser. This suggests specific further consideration of analytical models for the zone near separation. Given improved modeling of conditions in the vicinity of separation, even more accurate predictions of the primary flow characteristics are highly likely. (Modified author abstract)
