M7 Heat and Mass Transfer in Packed Beds with Fluid Flow

Numerical modelling of flow and coupled mass and heat transfer in an adsorption process

“…However, as both the heat and mass transport processes in the adsorbent layer are locally considered, there are both gas side and solid side resistances in the present 3D model. 13 …”

“…However, the majority of them (Ge et al, 2008) employed onedimensional (1D) models with only axial variation, utilizing empirical transfer coefficients to account for the transfer rates at the interface (Tsotsas, 1993;Tsotsas, 2010). Consequently the heat and mass transfer phenomena within the porous adsorbent are not described locally in a detailed way.…”

Heat transfer enhancement using porous material

“…The models and results presented in this paper would be useful for the optimum design of packed bed reactors. Tsotsas (2010a) [2] has well summarized the axial heat dispersion characteristics in the packed tubes. It is demonstrated that, axial dispersion of heat in packed tubes with fluid flow is not due to the effective thermal conductivity alone, but to a combination of heat transport in the direction of flow, heat transfer between particle surface and fluid, and heat conduction inside particles.…”

“…In this frame, the model of Zehner, Bauer and Schlünder [19] is used to define the effective thermal conductivity of the packed bed (k b ).…”
