Thanks Robin for your response.
What you assumed is definitely correct. No, I don’t have any paper or approach in mind. I was just wondering whether it is a good idea to use lubrication approximation in place of solving the actual problem without any approximation.
Navier-Stokes is a non-linear equation and hence difficult to solve for two or three dimensions without the approximation. But this is not the case with LBM (its part of the computer to do the calculation). So, Do you think its really a good idea to go for approximation?
Thanks.
