Abstract

The paper gives the analysis of calculation methods and results of calculating the intensity of heat transfer from the surface of round single tube, tube bundles in conditions of forced, free and mixed convection. The analysis shows the differences in results depending on the method of calculation. From a practical point of view these methods are used for calculating the heat transfer intensity for various types of heat exchange equipment. The most difficult situation is observed in the field of small Reynolds numbers. For certain types of layout (e.g. tube bundles) strict methods for calculating the heat transfer intensity in free and mixed convection are absent. The obtained results indicate the need for more complete study of heat transfer phenomena in mixed and free convection, especially in bundles of horizontal tubes
