The Strouhal number governs flow that arises due to these phenomena. Helmholtz is the namesake of three theorems that concern the physical shape of these objects, and when these objects possess no shear factor, their equation of motion shows that all points in them possess the same angular velocity. Theodore von Karman is the namesake of a sheet that shows how these objects can induce motion in fluids. For 10 points, name this phenomenon that is the namesake of a characteristic measured by taking the curl of the velocity of a fluid or taking circulation and dividing it

Theodore von Karman is the namesake of a sheet that shows how these objects can induce motion in fluids. For 10 points, name this phenomenon that is the namesake of a characteristic measured by taking the curl of the velocity of a fluid or taking circulation and dividing it by area, a fluid phenomenon that swirls.
