MEASURING LOCALHEAT TRANSFER COEFFICIENTCIRCULARCYLINDERIN A CHANNEL

Abstract

In the presentarticle examinesthe distributionof heatfrom thesurface ofa circular cyl- inderhas two varieties. In the first case, when, q<0,6afterthe minimumheat transfer coefficientgradu- allyθ=180° increases and reachesits maximum value.For largecluttered,when q > 0,7 maximumheatis shiftedfrom the front ofthe critical pointin the direction ofmiddle section, which is consistent with the resultsof theoretical calculations.

Keywords: heat exchange, round cylinder, laminar current, turbulent flow
