Determination of optimal design parameters of a heat exchanging section by numerical modeling

With the development of industry, the need to improve the efficiency of oil coolers is particularly increasing, due primarily to the rising cost of equipment, as well as increased attention to the issues of resource and energy saving. Oil coolers should not only perform the required functions of oil cooling, but also be as reliable and environmentally friendly as possible. Meanwhile, the majority of serial oil coolers are designed on the basis of outdated technical solutions, and this predetermines the levels of efficiency and reliability of their work as not corresponding to modern requirements. In this connection, the issues of hydrodynamics and heat exchange in finned tubes of oil coolers and refinement of methods of their calculation are relevant both for modernization of existing devices and for design of new oil coolers.
