The Dissipation of Heat by Free Convection From Vertical and Horizontal Cylinders

Abstract

attached to element surfaces are unsuited for measuring temperatures in convection circumstances since they seem to have a very pronounced effect on the temperature field. This, however, does not mean that appreciable overshoot does not occur under any circumstances. Ostroumov [2] observed overshoot using the same temperature-measurement technique employed in this work. However, he was considering the case of horizontal wires where such overshoot might eventually be explained as a result of a crossed bouyancy force and flow direction at the bottom of the wire. In conclusion, the conduction solution gives a good prediction of the temperature response of thin wires in liquids and, as far as it can be shown, in air. The simplified quasistatic solution gives reasonable predictions only for transients in air, and even here the conduction solution appears more accurate
