主 题:eddy viscosity tensor turbulent boundary layer with adverse pressure gradient new eddy viscosity modelling.
摘 要:A new eddy viscosity modelling of turbulence is proposed in ref. [1], whose characteristicsexpress the anisotropy of the turbulence stress. In ref. [1], the way of proposing somedistributional laws of the eddy viscosity tensor components is found from experimental re-sults for elementary flow of each kind of shearing flow, and then we can forecast thecomplicated shearing flows more accurately. In this way, the distributional laws of the ed-
