Cylinder in crossflow heat transfer
WebOct 1, 2004 · 1.. IntroductionThough there is considerable information on the local heat transfer distribution on a circular cylinder in crossflow of air, understanding of the influence of Reynolds number (Re) and Prandtl number (Pr) on such heat transfer with different fluids is still poor, especially on the rear part of a cylinder.Using data obtained … WebThe Eckert number phenomenon describes a reversal in heat transfer from a moving wall at an Eckert number Ec ≈ 1. In this report the Eckert number phenomenon is confirmed experimentally for the first time. For that purpose the heat transfer from a heated, vertically rotating cylinder in a cross-flow was investigated where the cylinder surface ...
