1. This implies that a potential flow is an irrotational flow . 2. The vorticity of an irrotational flow is zero. 3. The flownet is an important tool in analysing two-dimensional irrotational flow problems. 4. In deriving the Kutta Joukowski theorem, the assumption of irrotational flow was used. 5. For an irrotational flow , the flow velocity can be described as the gradient of a velocity potential. 6. An irrotational flow means the velocity field is conservative, or equivalently the vorticity pseudovector field is zero: 7. From here, two opposing processes occur : ( 1 ) irrotational flow and ( 2 ) secondary flow. 8. In irrotational flow , total pressure is the same on all streamlines and is therefore constant throughout the flow. 9. "' Irrotational flow "': From Bernoulli's equations, high pressure results in low velocity. 10. Now, for irrotational flow the velocity is the gradient of the velocity potential, and the local Mach number components are defined as:
