| Title of the article | Computer simulation of fluid flow and heat transfer in conical coiled heat exchangers of the «pipe-in-pipe» type |
| Abstract. | Problem statement. The aim of the work is to numerically simulate the processes of hydrodynamics and heat transfer in conical coil heat exchangers of the «pipe-in-pipe» type with a heat-exchange element in the form of a smooth pipe, to assess the energy efficiency of such devices. Results. The main results of the study are that in the course of the work, the authors developed a model and an algorithm for calculating tapered coil heat exchangers of the «pipe in pipe» type, implemented in the Ansys program, and determined the thermo- hydrodynamic indicators of the coil devices. Conclusions. The significance of the results obtained for the construction industry lies in the possibility of using modern, more efficient and compact heat exchange equipment for the technological needs and justifying this choice. Therefore, with equal initial data, conical heat exchangers are more efficient in comparison with cylindrical ones with a heat exchange element in the form of a smooth tube, since they have a smaller heat exchange surface to achieve the required thermo- hydrodynamic parameters. |
