Mathematical Model and Numerical Solution of the Heat Transfer Process in the Solid Adsorption System

LIU Hua-xiang 1, ZHANG Xue-jun 2 (1.Institute of Mathematics and Informatics,Jiangxi Normal University,Nanchang 330027,China;2.School of Power and Energy, Shanghai Jiao Tong University,Shanghai 200030,China)  
In this paper, a theoretical analysis of the heat transfer process in a adsorber model is developed. For transient heat conduction in the bed, the unsteadystate Fourier heat conduction equation is applied. Based on some assumptions, boundary conditions and the energy governing equation of the fluid in the cartridge heater are obtained. By the application of control volume approach and implicit central difference scheme, the heat conduction equation and the energy governing equation are discretized, and finite difference equations for the pillar adsorber are derived for simulative numerical solution by computer. In comparison with other calculation models, the boundary condition is dependent on time and tallied with the actual situation more, and the conjugated temperature field in the bed and tube is obtained.
