The present study reports on an analysis of the sensitivity of condensation heat transfer coefficient correlations on the simulations of the performance of steam surface condensers. Five correlations of heat transfer coefficient for filmwise condensation are tested against the experimental data for a ...
The design of steam and hot water injection projects requires estimation of casing temperatures and wellbore heat losses. Several authors have shown that well bore heat losses and casing temperatures can be calculated if the overall heat transfer coefficient is known. A brief derivation is presented ...
The following work for steam condensing on the outside surface of a 3 4 in OD × 5 8 in ID × 12 1 2 in long copper tube has verified the effect of the inclination of the cylinder on the heat-transfer coefficient as predicted by the above theory. The experimentally determined ...
