WebThe phenomenon of flow channeling in packed beds is investigated in the present analysis. A closed-form solution is obtained from the volume-averaged second-order momentum equation with the no-slip condition at the wall, using an exponential porosity distribution typical of packed beds. WebIn chemical engineering, chemical reactors are vessels designed to contain chemical reactions. The design of a chemical reactor deals with multiple aspects of chemical … WebThere are three types of porosities used to describe a packed bed (a) Intraparticle porosity (εp): the fraction of the column volume occupied solvent inside the pores of the support or directly in contact with its surface (i.e., the stagnant mobile phase). data in mongodb is represented in

"WebChanneling in single-phase flow can occur along walls or any other low voidage region, for example, if settling occurs in a horizontal bed. Channeling in two-phase flow can result from even more complex causes, and as seen simple two-phase flow theories seldom predict pressure drops in packed beds. " - Reactor channeling
