Irrotational Flow
 

hi Can anybody tell me how to simulate an irrotational(inviscid i am doing at present) flow in fluent.

Please see,

hi jin Define-->Model-->Viscous defines only an inviscid flow but not irrotational. So kindly help in this direction. Regards Sudeep Bosu

Re: Irrotational Flow
 

When flow is irrotational, doesn't that imply it is invsicid? The element of a fluid does not have rotation because there is no viscous sheer force. Am i incorrect (I may be, this is a confusing topic that I have not touched lately).

Anyone want to redefine irrotational flow for us?

Re: Irrotational Flow
 

Irrotational flow is the further simplification of inviscid flow. The assumption is vorticity equals zero. If the velocity field is irrotational, it can be represented simply as the gradient of the scalar function (velocity potential), which leads to Laplace Equation. Hi, Sudeep, if you can solve your problem as inviscid flow problem, why do you want to do it as irrotational flow?

hi michael I am using Fluent to validate a inverse design code i have developed.The code assumes irrotationality but in the Fluent domain i am getting free voticies will distort my surface velocity distribution. Sudeep Bosu
