Heat and mass transfer simulation of screen finned plate-fin absorber

Abstract

This paper proposes a new type of absorber—screen finned plate-fin absorber. The paper introduces the structure of the absorber. A heat and mass coupling model of single screen falling film absorption process has been established. The average temperature and concentration distribution has been abtained by numerical calculation. And the paper analyses the impacts of the length and the angle on heat and mass transfer. The research would be very valuable in learning the falling film absorption process mechanism of the screen finned plate-fin absorber, and also in the design of the absorber.
