A mathematical model of heat transfer in apparatus of air cooling of oil

Abstract

In this paper the boundary value problem describing the process of unsteady heat transfer in apparatus of air cooling of oil is formulated and solved. Different modes of operation of such heat exchangers are modeled. The analytical solutions of the boundary value problem corresponding to different modes of operation of apparatus of air cooling of oil are obtained.
