ABSTRACT

Within the framework of multiblock approach, using a finite-volume algorithm based on the physical-process splitting concept and developed for the solution of three-dimensional nonstationary Navier-Stokes equations, a numerical analysis of spatial separated flow playing a dominant role in the mechanisms of heat transfer enhancement is carrier out. Special attention is given to computer identification of self-organizing jet-vortical structures. The correctness of the developed approach is checked in comparison of numerical and physical results for a turbulent flow in a channel with a lune. The structure of a vortical flow in the vicinity of the lune on a flat wall is numerically analyzed. The connection between reorganization of a vortical structure in the asymmetric lune growth of thermal output is found out.
