ANALYSIS OF THE RAYLEIGH NUMBER IN THE AREA OF STEEL RECTANGULAR SECTIONS IN THE CONDITIONS OF STEDY AND UNSTEDY HEAT FLOW
Journal Title: Civil and Environmental Engineering Reports - Year 2014, Vol 3, Issue 14
Abstract
The paper presents the experimental measurements dedicated to the research for the Rayleigh number (Ra) in the area of rectangular steel sections. This problem is associated with the analysis of the free convection which takes place in the heating of sections bundles during the heat treatment. The study was conducted for both steady and transient heat transfer. The values of the Ra number obtained for the tested sections allow to describe the phenomenon of convection on the basis of a very simple criterial dependence. It greatly simplifies the mathematical description of the heat transfer phenomenon in the concerned charges.
