WebIrrotational Flow Flow is said to be irrotational when the vorticity has the magnitude zero everywhere. It immediately follows, from Equation ( 4.77 ), that the circulation around any … Webcharacteristics of the fluid simply eliminates the (1/2) factor associated with the rotation vector. If ∇×=V 0 , the flow is called irrotational. In addition to the rotation associated with the derivatives ∂u/∂y and ∂v/∂x, these derivatives can cause the fluid element to undergo an angular deformation, which results
