Webwhere ΔP is the pressure drop (Pa), ΔL is the height of bed (m), V is the velocity of fluid (m/s), ε is porosity (the ratio of volume of voids in the bed to the total volume of the bed), q is the density of fluid (kg/m3), µ is the viscosity of fluid (kg/m.s), D p is the effective mean diameter of the particles (m), and ɸ is the shape factor. WebFor an accurate prediction of the porosity of a liquid-solid homogenous fluidized bed, various empirical prediction models have been developed. Symbolic regression machine learning techniques are suitable for analyzing experimental fluidization data to produce empirical expressions for porosity as a function not only of fluid velocity and viscosity …
