length of recirculation zone
i was examining the velocity flow pattern and recirculation zones in a t-junction with two different meshing(one a coarser one and the other is the finer one) in fluent. But i am facing a problem in fluent that the length of recirculation zone with coarser grid is more reasonable than that with finer grid at same reynolds number. All the operating conditions as well as grid parameters have been kept same except the extent of meshing(fine and coarse). Please help me out.
