Research Abstract

High efficiency of gas absorption is one of the important techniques for the protection of global environment. In our previous paper, a new concept of physical gas absorption by utilizing condensation process and mist formation was proposed and its proof experiment was conducted. In the condensate method for gas absorption, it is a remarkable feature that the mass transfer rate of soluble gas such as Carbon Dioxide are affected practically by the diffusion process in the mixed gas with faster diffusivity than in the solvent liquid. Consequently the rate of gas absorption by this method is faster compared with the conventional physical methods such as the falling liquid film method. And it was clarified that the rate of gas absorption by means of this methods depended mainly on the condensate film. On the other hand, in the forced convection condensation inside a vertical cooled tube, in which the flow direction of vapor is against gravity force, the surface of liquid condensed on the cooled wall becomes wavy, and various phenomena such as flooding, droplet entrainment and pulsation of condensate could appear in a tube. Therefore, it is expected that the enhancement of condensation heat transfer by the counter-current wavy flow in a tube might be available to get the higher performance of the absorption system.
From this view point, in this study, as a basic research for the development of a high-performance and environment-friendly thermal energy recovery system, detailed investigations have been conducted to understand the possibility and the mechanism of die enhancement of gas absorption and condensation heat transfer by the countercurrent wavy flow.
