Abstract

Forced convection heat transfer and pressure drop for cooling water which pass into condenser tubes is investigated numerically and experimentally, The study is dependent on the effect of the rings with different inner diameter placed inside the tube at different distances. The outer surface of the tested condenser tube is heated by saturated steam at atmospheric pressure. By using one integrated a computational fluid dynamic software (CFD) is the fluent theoretically investigated. The software is used to solve the governing equations for flow; which are continuity equation, momentum equation and energy equation, the distribution of the heat transfer coefficient and the pressure drop along tube length, can be obtained and consequently the average heat transfer coefficient. The theoretical study was performed for the cases of a tube without rings and with rings. To perform the experimental study, an experimental apparatus is designed and constructed .It consists of a copper tube ,where the cooling water p < strong>asses inside it and the outer surface of the tube is heated by saturated steam at atmospheric pressure. The apparatus is equipped with the required sensors to measure the tube outer surface temperature. flow rate and pressure drop. The experimental and numerical results showed that the use of rings increasing the heat transfer coefficient rather than that of tube without rings and the rings of inner diameter 8mm increase average heat transfer coefficient up to 66%. There is an acceptable agreement between the numerical and experimental results.
