Modeling and numerical analysis of evaporative condensing regenerator

Abstract

A two-dimensional steady state model was developed and solved numerically to predict the performance of evaporative condensing regenerator. Two-dimensional parameter distributions of air, solution and refrigerant were calculated by the mathematical model. The solution content first increases and then decreases along the solution flow direction. At y/H_r=0.98 (where H_r is the height of regenerator), air humidity increases from 1.99% to 2.348% firstly and then decreases. The experimental results were used to validate mathematical model. It is indicated that the simulation results agree with experimental data well. The results not only show that the mathematical model can be used to predict the performance of regenerator, but also has great value in the design and improvement of evaporative condensing regenerator.
