DETERMINATION OF OPTIMAL DESIGN PARAMETERS OF A HEAT EXCHANGING SECTION BY NUMERICAL MODELING

DOI: 10.17804/2410-9908.2022.2.045-054

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 Meanwhile, the majority of serial oil coolers are designed on the basis of outdated technical solutions, and this predetermines the levels of efficiency and reliability of their work as not corresponding to modern requirements.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.

Keywords: mathematical modeling; coupled heat exchange problem; optimization problem; oil coolers; cooling system

С развитием промышленности, необходимость повышения эффективности работы маслоохладителей особенно возрастает. Это связано в первую очередь с увеличением стоимости оборудования, а также повышенным вниманием к вопросам ресурсо- и энергосбережения. Маслоохладители должны не только выполнять требуемые функции по охлаждению масла, но и быть максимально надежными и экологически безопасными. Между тем большинство серийных маслоохладителей разработаны на основе устаревших технических решений, что определяет уровни эффективности и надежности их работы, не соответствующие современным требованиям. В связи с этим вопросы исследования гидродинамики и теплообмена в оребренных трубках маслоохладителей, а также уточнение методик их расчета являются, актуальными как для модернизации существующих аппаратов, так и при проектировании новых маслоохладителей.

Ключевые слова: математическое моделирование; сопряженная задача теплообмена; задача оптимизации; маслоохладители; система охлаждения
