文摘Non-isotropy is evident for flows with large streamline curvature. Algebraic stress model can fairly simulate non-isotropy of turbulence. Some flow situations were investigated with a well developed ASM model. The calcu- lated results show that the distributions of Reynolds stresses in different directions are obviously different. The non-isotropy of the flow is evident. The effect of streamline curvature on the flow feature of submerged water jet restricted by solid boundaries were studied, and its application in the design of energy dissipators of free trajectory jet type was disscused.
