NUMERICAL ANALYSIS OF THE INFLUENCE OF THE DEPTH OF A SPHERICAL HOLE ON A PLANE WALL ON TURBULENT HEAT EXCHANGES. A. Isaev,a A. I. Leont'ev,b P. A. Baranov,a and I. A. Pyshnyib UDC 532.517.4:536.24 A numerical investigation of the influence of the depth of a spherical hole on a plane wall on vortex heat exchange has been carried out within the framework of the multiblock approach to solution of the steady-state Reynolds equations closed with the help of Menter's zonal model of shear-stress transfer and the energy equation. aAcademy of Civil Aviation, St. Petersburg, Russia; email: isaev@SI3612.spb.edu; bN.
