An experimental investigation of decelerating flow about two-dimensional cambered plates
Technical Report

OSTI ID:5646627
Impulsively-started uniform flow, decelerating at specified rates, about two-dimensional cambered plates with included angles of 120, 180, and 240 degrees has been investigated experimentally in a vertical water tunnel. The forces acting on the plates have been determined as a function of the relative displacement of the fluid at subcritical Reynolds numbers. The evolution of the vortices was visualized by means of various dyes and polystyrene beads. The variation of the drag coefficient with time is interpreted in terms of the formation, growth, and motion of vortices. 15 figs.
