I had gone through sukops book and came a cross a point in page number 66 which said that maximum velocity should be limited to 0.05 lu/ts elsewhere it is also mentioned that it should less than 0.1 lu/ts . can someone explain what is the basis for this constraint? what is the maximum range of reynolds number that this model can solve sucessfully?
Having gone through the matlab code for lid driven cavity i wanted to try out poiseulle flow wid pressure boundary conditions but for a given random problem it was very difficult to keep the maximum velocity down to the above value. so it would be of good help if someone annswered my above issues and gave me 2 things?
- actual physical units of lid driven cavity problem solved in code?
- A random poiseullie flow problem anyone has solved before with pressure boundary conditions having physical units?
