| Title of the article | Visualization process of fluid flow and heat transfer in tubes with helical heat exchange surface |
| Abstract. | One of the ways to create efficient heat transfer devices is to use them in the heat exchanger elements with a twist flow. In this regard, recently has been actively working to create channels using the effects of spin currents. We previously proposed the heat transfer elements of the type «confuser-diffuser» with spiral heat exchange surface. In this paper we attempt to perform computer simulations of fluid flow and heat transfer using imaging flow patterns in the running part of such elements. Computational study was conducted with the help of the program complex Solid Works Flow Simulation for pipes with different dimensions. The values of the distribution of the velocity field, temperature and pressure in each of the computational domain and the comparative analysis of heat and hydrodynamic efficiency considered pipes. The values of heat transfer coefficients in the flow of the channels and proven promising tubes with helical heat exchange surface for design of energy-efficient heat exchangers. |
