Numerical simulation of heat-transfer fluid warm-up in heating facilities with heat transfer augmentation achieved with swirling flow

Abstract

Swirling flow of heat transfer fluid in heating facilities is a compelling way to intensify heat transfer augmentation. The paper considers the process of passive swirling flow in heating pipes by way of application of special design pipe connectors. Numerical simulation has been accomplished on the basis of viscous incompressible fluid model represented by Navier-Stokes equations complemented with temperature transfer equation. Numerical experiments has been completed with the help of applied software OpenFOAM based on finite volume method.
