WebForced Vortex Flow If there exists a solid body rotation at constant ω (induced by some external mechanism), the flow should be called a forced vortex motion (Fig. 3 (b). We can write Equation (10) predicts that 1. The circulation is zero at the origin 2. It increases with increasing radius. 3. The variation is parabolic. WebThis experiment is related to the free and forced vortex flow of fluid in rigid-body rotation within a cylindrical tank. As mentioned in paragraph 1, vortex is the rotation of fluid elements around a common center. Mostly the fluid flows in a spinning motion about an imaginary axis, straight or curved. That motion pattern is called a vortical flow.

"A key concept in the dynamics of vortices is the vorticity, a vector that describes the local rotary motion at a point in the fluid, as would be perceived by an observer that moves along with it. Conceptually, the vorticity could be observed by placing a tiny rough ball at the point in question, free to move with the fluid, and observing how it rotates about its center. The direction of the vorticity vect… " - Forced vortex flow
