| Title of the article | Improvement of heat exchange devices of the type «pipe in pipe» with rotating heat-exchange surface «confusor-diffusor» and ribbed flowing part |
| Abstract. | The class of heat exchange devices with a flowing part confusor-diffusor is analyzed. Approaches of improvement of their designs are offered. Approaches are based on the use of passive methods of intensification. Methods are: the edge of a flowing part, channel profiling for the purpose of impact on interface at a channel wall concerns. Methods of research of the interfaced problem of heat exchange and hydrodynamics in such channels are analyzed. Computing schemes for the approximate decision are constructed. So, numerical realization was carried out by a method of final elements, and the method of penal functions was applied to determination of pressure. Results of numerical research are given. Universality of the use of devices offered by authors, in the wide nomenclature of rotational devices and gravitational heat exchangers for modernization of existing park of the heat exchange equipment by replacement of smooth heat exchange elements with confusor-diffusor pipes in cover-tubular heat exchangers is shown. |
| Keywords. | Heat exchange, confusor-diffusor, the edge. |
