摘要：

Results are given of numerical simulation of hydrodynamics and heat transfer under conditions of transverse flow past a two-dimensional "trench" (a groove whose cross section has the form of a segment of circle) located on a plane isothermal surface. The calculations are performed for an incompressible liquid within two-dimensional Reynolds equations closed with the aid of the Menter and Spalart-Allmares turbulence models using multiblock overlapping grids. Detailed analysis is performed of the effect of the trench depth on the flow structure (configuration of separated-flow regions) and on the distribution of friction, pressure. and heat fluxes along the surface subjected to flow.
