Abstract

The results of a numerical simulation of the convective heat exchange in a lane bank of round tubes in the case of laminar flow of an oil about it are presented. The Navier–Stokes and energy equations were solved using the multiblock computational technologies realized in the VP2/3 package. It is shown that, in the case of laminar M20- oil flow about a round-tube bank (of size 2 × 1), the convective heat transfer in it is ten times larger than in the case of air flow about this bank and that the velocity of the separation flow increases by two times with increase in the temperature of the tube wall from 20 to 40°C.
