WebFeb 15, 2024 · An accurate numerical model is proposed to simulate flow through cylindrical fixed-bed reactors with randomly packed porous non-spherical particles. The length scale for flow outside the porous particles (made of open-cell foam) is higher than the size of the internal micro-pores of the particles. WebJan 1, 2011 · Fixed bed reactors are widely used in the chemical and process industry amongst others for catalytic surface reactions. The design of such reactors is often done with simplifications, e.g. with the assumption of plug flow and an equally distributed porosity over the whole fixed bed.

WebA bed with a height 2.5 m and an internal diameter of 0.035 m is packed with cylindrical particles of diameter D p = 0.003m. The void fraction of the bed is ε = 0.33. A gas of density ρ = 0.9487 kg/m 3 and dynamic viscosity μ = 3.1 × 10 −5 Pa s flows through the bed with a superficial mass flow velocity of 1.4 kg/m 2 s. Determine the ... WebFeb 2, 2024 · This manuscript presents a simplified method of modeling fixed-bed reactors based on the porous medium. The proposed method primarily allows the necessity of precisely mapping the internal structure of the bed—which usually is done using real object imaging techniques (like X-ray tomography) or numerical methods (like discrete element … kids free bowling program
