Abstract. In modern conditions, heat-exchange equipment is widely used in technological processes that require high energy efficiency. Studded surface is a very common form of extended surface for the heat transfer. At present, modeling is an economically justified tool for developing new constructive solutions aimed at improving efficiency of the heat transfer in addition to the physical experiment. The objective of the study was development of a numerical model capable of describing adequately the heat transfer with studded surface. Adequacy of the developed model is confirmed by comparison of the obtained data with the results of the experimental study.
Key words and phrases: тепломассообмен, ошипованная поверхность, расчетная сетка, рекуператор, кольцевой канал, heat and mass transfer, studded surface, computational grid, recuperator, annular channel
