Title of the articleMathematical modeling of heat transfer surfaces of spring-twisted channels
Abstract.Problem statement. When developing the heat exchange equipment many methods of an intensification of heat exchange are used. One of perspective is the method when the form of a heat exchange surface changes. In this regard the class of spring and twisted tubes which have high power efficiency is interesting, allow to modernize and reconstruct the existing heat exchange devices without essential capital expenditure. Results. In work the mathematical model allowing to describe and construct heat exchange surfaces of pipes of difficult configurations is offered. Varying the parameters entering mathematical model it is possible to conduct a full research and optimization of internal geometry of the considered pipes. Conclusions. The significance of the obtained results for the construction area is that the proposed heat exchange elements are installed in innovative heat exchangers installed in individual heat points. In addition, the proposed mathematical models describing the surfaces of spring-twisted channels can be used not only in the development of modern heat exchange equipment, but also in construction in the design of various structures, as well as in the design of connecting surfaces of sections of pipelines of different diameters.
Keywords.surface, hydromechanics, heat exchange equipment.
