RESEARCH OF INFLUENCE OF THE FORM OF FINS ON THE FLOW DYNAMICS AND THE CHANNEL RESISTANCE

Menyalkina Ekaterina Nikolaevna
Samara State Technical University


Abstract. The article deals with influence of the form of fins on the flow dynamics and the channel resistance of the heat exchanger. The study was carried out by numerical modeling methods for the plane-parallel channel with geometrically similar fins of three different forms for various values of the Reynolds number. As a result of the research, dependence of the characteristic of hydraulic resistance of channels on the value of the Reynolds criterion was identified. The optimal form of channel fins, which can be used for further studies of heat exchange intensification, is determined.
Key words and phrases: интенсификация теплообмена, гидравлическое сопротивление, оребрение, численное моделирование, теплообменное оборудование, intensification of heat transfer, hydraulic resistance, fins, numerical modeling, heat transfer equipment.
