k-epsilon model - low yp+ -- CFD Online Discussion Forums

December 29, 2020, 04:31	k-epsilon model - low yp+	#1
alextau New Member Alexander Yurishchev Join Date: Feb 2019 Posts: 21 Rep Power: 7	Hello, I am running two-phase turbulent simulations in ducts. I understand that the first cell thinkness yp+ should be larger than 30 for k-epsilon model. However, due this setting my mesh is extremely coarse. For finer mesh I want to set yp+~1-5. I am wondering if yp+~1-5 is suitable for k-epsilon model or should I use komegaSST model? Thank you, Alex.
