Abstract

This study aims at simulating the flow in a ribbed double pipe heat exchanger both numerically and analytically and to analyze the accompanying thermo fluid mechanisms. Two procedures were developed to model the heat transfer and the pressure drop, analytical and numerical. The analytical procedure employs empirical equations and correlations governing the flow. The equations were compiled in a MATLAB code to be solved. The numerical procedure is based on simulating the flow using FLUNET to obtain details of the velocity, temperature and pressure distribution across the flow channel. These values were then used to evaluate the friction fuctor and Stanton number from their fundamental relations using MATLAB The results from both procedures showed good agreement with the experimental results. At a Reynolds number range of 2000-20,000 , heat transfer was found to be enhanced by more than 4 times at an expense of increasing pressure drop of more than 26 times.
