I calculated an air flow in a tank using "pitzDaily" tutorial of OpenFOAM.
The result seems to be something strange turbulent eddy (see the pictures on the URL below. The difference of the two results is the number of cells). I calculated this using hexamesh of "Body Fitting" algorism of SALOME. https://www.dropbox.com/s/z7aplky49tpy6lj/vessel1_47-u%26p%282%29.png?dl=0 https://www.dropbox.com/s/l2nucr7pj27fdpu/vessel1_50-u%26p%282%29.png?dl=0 Are these eddies valid? If not, what are the reasons of these eddies generating? Mesh? Solver? When using tetramesh of "Nitgen 1D-2D-3D" algorism, the below result was obtained. The eddy is not so strange. https://www.dropbox.com/s/q7ps09otakyb4ur/vessel1_8-u%26p%283%29.png?dl=0 I'm looking forward to your comments. KeiJun |
