  • 1505 DNS of a turbulent boundary layer with separation and reattachment : analysis of Reynolds stress budgets

抄録

Direct numerical simulations (DNSs) are used to analyze a flat-plate turbulent boundary layer with separation and reattachment. In the present DNSs, the strong blowing and suction are imposed at the upper boundary for producing a large turbulent separation bubble, thus dealing with massive separation. Particular attention is given to the Reynolds stress budgets and the similarity to those in a backward facing step.
