RECONSTRUCTION OF THE VORTEX-JET STRUCTURE OF THE SEPARATION TURBULENT FLOW IN A SPHERICAL DIMPLE ON THE WALL OF A NARROW CHANNEL WITH INCREASE IN THE DEPTH OF THE DIMPLE AND INTENSIFICATION OF THE SECONDARY FLOW IN IT

摘要

On the basis of an analysis of the reconstruction of the vortex-jet structure of the completely developed turbulent flow of an incompressible fluid in a spherical dimple on the wall of a narrow plane-parallel channel with increase in the depth of the dimple, a map of regimes of separation flow around such a dimple at a Reynolds number of 40, 000 has been developed with special emphasis on the intensification of the multivortex flow formed in the indicated dimple in the case where a symmetric flow in it is changed to the axisymmetric one.
