ABSTRACT

This paper studies both numerically and experimentally the phenomenon of heat and mass transfer occurring in an adsorptive fixed bed. The experiment consists of a cylindrical column filled with uniform grain silica gel subjected to humid airflow. The computer code developed for this work simulates the influence of some physical and geometrical parameters derived from the adsorptive and regenerative processes that occur in packed beds during dehumidification. It was used as a one-dimensional, transient, and nonisothermal model. The equations were discretized via finite volume method, fully implicit formulation, and colocated arrangement. Linear systems have been solved by the Thomas algorithm. The experimental and numerical results are described as temperature profiles along three different speeds observed during regeneration and under various conditions of relative humidity at the adsorptive bed outlet. These results are consistent with the physical conditions of the desired outlet.
