Mass flux - Wikipedia

WebThe first term on the right-hand side represents the diffusive mass flux; the second term expresses the convective mass transfer, which results from the permeation of the bulk flow. This convective flow does not involve any convective bulk flow due to the pressure difference on the two sides of a porous membrane. WebApr 22, 2024 · 1/If the flow morphologies are assumed to be "continuous" either symmetric or gradient or user defined are the way to go. 2/If you want to write an UDF for mass transfer it should return the mass flow per unit volume and not the mass flux (per unit area). So your UDF should return the mass flux * Interfacial area as single expression. greek grocery store montgomery al
