Analysis for cell restriction at the wall Now we wonder what should be the size of the near wall cellsWe consider theory based on flat plate analysisUsing the wall functions it may be sufficient to put We look for meeting () for Friction coefficient of turbulent boundary layer on the flat plate is known (correlation of measurements and DNS simulations)For fast estimation: = More accurate estimation is:(7.5)For , , = So, finally the minimal cell height (the wall normal direction size) is Previous: Generally about meshes for Up: Mesh generation Next: OBJ model preparation OpenFOAM Training by CFD Support, CFD SUPPORT, info@cfdsupport.com +420 212 243 883 © CFD support, s.r.o., Sokolovská 270/201, 190 00 Praha 9, Czech Republic
