Oldroyd-B model using Finite Difference
 

Hi dear friends !

I would like to know if in this forum someone works with Viscoelastic Flows Oldroyd-B using Finite Difference. Particully, I'm concerned with Boundary Conditions for Free Surface and Rigid boundary.

Ps: I've seen Finite Element Techniques in many and many papers. However, papers in the Finite Difference context is scarcely.

Thanks!

Dear Friend,

Please, read the following paper, :

"The Effect of Hydrodynamic Conditions on Heat Transfer in a complex viscoplastic flow field" by Khaled J. Hammad Int. Journal of Heat and Mass Transfer, 2000)43, pp. 945-962.

I think, this paper may be help you. Thanks
