Summary

UNLIKE THE ORDINARY PARALLEL FLOW, THE STREAMLINE OF SWIRLING FLOW TWISTS HELICALLY DOWNSTREAM, WHICH MAY CHANGE THE STRUCTURE OF FLOW IN WALL REGION AS IS EXPECTED FROM THE STUDY OF STREAMLINE CURVATURE EFFECTS OF A TWO-DIMENSIONAL CURVED FLOW. EFFECT OF STREAMLINE CURVATURE IS CHARACTERIZED BY A PARAMETER, NONDIMENSIONALIZED ANGULAR MOMENTUM FLUX, BY WHICH THE FLOW IS CLASSIFIED AS: NOT, PARTIALLY, AND COMPLETELY INFLUENCED, ACCORDING TO THE MAGNITUDE OF THE PARAMETER. THE FLOW IS FOUND TO BE THREE-DIMENSIONAL WHEN THE PARAMETER SURPASSES 0.186.
