VISUALIZATION OF A FLOW IN A SPHERICAL DIMPLE BUILT IN THE LOWER WALL OF THE RECTANGULAR-SECTION CHANNEL OF A WATER TUNNEL AND NUMERICAL IDENTIFICATION OF THE VORTEX-JET STRUCTURES IN IT

Numerical and physical simulations of a laminar separation flow over a single spherical dimple built in the lower wall of the rectangular-section plane-parallel channel of a water tunnel were performed on the basis of the multiblock computational technologies realized in the VP2/3 package. The vortex mechanism of intensifi cation of the heattransfer processes in this dimple was analyzed with special emphasis on the identifi cation of the vortex-jet structures self-generated in it.
