A mathematical model for predicting spray/wall interaction in swirling flows of a direct-injection (DI) diesel engine is developed using a centre-line velocity vector/continuum approach. Generalization of the integral method for solving continuity and momentum equations for both free and wall regions of spray motion is demonstrated. The compression-induced swirl is estimated taking into consideration the wall friction and the exact moment of inertia of cylinder-piston assembly. The predictions are found in general agreement with the results of other workers.
