Fluid flow through catalyst filled tubes
WebFluidized Bed Reactor. In chemical industries fluidized bed reactors are used for solid gas reaction. In this we use gases as a fluidizing media to fluidize the solid catalyst, which is a bed of finely divided solid particles. This fine powder is contained in a cylindrical vertical shell, having a grid at the bottom to support the catalyst bed ...

WebJun 15, 2024 · Multiphase flow involving gas and liquid phases forms the most common type of flow in industrial processes that apply porous or structural packing. The role of the porous structure can be taken on by open–cell solid foams, including open–cell metal foams. WebNuclear magnetic resonance (NMR) techniques were used to measure non-invasively the ensemble-average velocity profile of water flowing through a tube filled with an open-cell rigid foam of high porosity (ϕ = 0.972).
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 …
