EXPERIMENTAL INVESTIGATION OF TURBULENT HEAT TRANSFER ALONG A CYLINDER
Abstract
The report presents experimental data on local heat transfer of a cylinder d= 4 mm, cooling in longitudinal turbulent air flow, experiments covered Re from 105to 5×107 and temperature factor Tw/Tf from 1,1 to 4. Using previous results for a cylinder 15,5 mm diam. general relations are derived for local heat transfer, accounting for the influence of temperature factor and cylinder transverse curvature.
