CFD-MODELING OF THERMAL AERODYNAMIC CHARACTERISTICS OF SCREW TUBES

Abstract

The article is devoted to the analysis of the flow in the middle of the propellant tube under non-isothermal conditions.
Such pipes are planned to be used as heating surfaces for condensers, steam heaters, air heaters for industrial boilers,
for example, E-50-4-440G.
The study of heat aerodynamic characteristics and strength of a brass spiral tube with an evenly developed surface at
an internal flow of air flow by means of CFD-modeling is carried out. The purpose of the work is to determine the optimal
geometric characteristics of propeller tubes, which are planned to be used for the creation of a heat exchanger. The
CFD-modeling data verification was carried out using a comparison with the test task known from the literature.
