Performance Analysis of a Row of Horizontal Tubes of an Evaporative Tubular Heat Exchanger
Pages : 92-98
The results of experimental investigations on mass transfer coefficient and evaporative effectiveness of evaporative tubular heat exchanger are presented in this article. Evaporative effectiveness is estimated over a wide range of operating conditions. Based on the experiments, correlations derived using the multiple regression analysis. Developed correlations and experimental data show that as the film flow rate increases, Evaporative Effectiveness and mass transfer coefficient increases provided that the air flow rate is constant which is flowing from underneath the tubes of the evaporative tubular heat exchanger. The tubes are subjected to simultaneous flows of cooling water from the top; air flows from underneath with controlled amount of humidity and the process fluid is flowing through the tubes. Developed correlations are helpful in improvement of the design of heat transfer devices and many other engineering applications.
