Simulation of heat Carrier Motion in Tubular Heating Radiators

Abstract

Statement of the problem. The movement of the coolant in sections of tubular heating radiators of original designs containing various types of turbulators is considered. It is necessary to develop models of the movement of the coolant in the structures under consideration in the speed range of 0.5—1.5 m/s and compare the intensity of flow turbulence in them. Results. Using the Flow Simulation module of the SOLIDWORKS software package, the results of modeling the movement of a coolant in sections of original tubular heating radiators with turbulent inserts were obtained. 3D models of radiator sections were built. The dependences of the Re number on the coolant velocity and the distribution of turbulence intensity in the radiator sections are given. Conclusions. Based on the results of the simulation, the designs of the sections of the original tubular heating radiators were compared with the standard ones. A turbulent insert providing the highest Re number and turbulence intensity in the radiator section has been determined.
