| Title of the article | Modelling of turbulent flow in straight line spring-twisted channels |
| Abstract. | The article deals with a steady turbulent flow of a viscous incompressible fluid in a twisted spring channel. The surface of this tube is a channel that is used as a taut spring coils is rigidly fastened. The surface of the channel under consideration is described vector-parametric equations derived on the basis of fundamental principles of analysis and differential geometry. The mathematical model of a viscous incompressible fluid is constructed in the Cartesian coordinate system based on the Reynolds equations, closed by the turbulence model, taking into account the characteristics of the channel geometry. The solution of the resulting system of equations with the boundary conditions will determine the parameters of velocity and pressure in the flow part of the channel and can be used to optimize the technological characteristics and geometric parameters of the existing heat exchangers, as well as creating new and promising designs of heat exchange equipment. |
