| 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:
