boundary condition of wall driven cavity flow
 

hi friends i need to boundary condition of wall driven cavity flow. please help me.

Re: boundary condition of wall driven cavity flow
 

hi,

here is the boundary condition u have to give.

I am assuming a square cavity.u have walls on three sides and upper wall is moving with some velocity. u=v=0 on all the three sides. for the upper wall u=some value (5 m/s say),v=0.wall is one streamline so si=some value(0.5 say) on all the walls(left,right,top,bottom).u have to calculate vorticity with these values for all the walls(if u can't find let me know i will tell u). An example problem is clearly explained in "CFD by hoffmann and chiang". If u need any help u can ask me. I have written a code for ur problem.
