mass transport process apart from diffusion (for example, convective solute flow or something like that) comes into play. The fact will be illustrated here below. 3.1 Continuous growth model (CGM.... In this case (as well as in case 2), the solute concentration and temperature fields are governed by the classical (local equilibrium) transport equation of parabolic type. 4) v≤vDb. Non-equilibrium......
and Environment Engineering, University of Science and Technology Beijing, Beijing 100083, China) Abstract: The solute transport process and the transport mechanism were studied due to its complexity and variability. The uniform flow model for solute transport was presented based on the assumption of ideal flow in heap. The mobile-immobile model was set up by considering the interaction and influence between......
