Comparison of split-operator methods for solving coupled chemical non-equilibrium reaction/groundwater transport models

Barry, D.A.; Bajracharya, K.; Crapper, M.; Prommer, H.; … - In: Mathematics and Computers in Simulation (MATCOM) 53 (2000) 1, pp. 113-127

Numerical models of reactive solute transport in groundwater are often solved using an approximate two-step approach that separates the transport and reaction processes. Even though the transport and reaction steps are split, using a novel formulation it is possible to pose the reaction step in...

Adsorption–desorption kinetics of the monomer–dimer mixture

Boscoboinik, J.A.; Manzi, S.J.; Pereyra, V.D. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 7, pp. 1317-1328

, when processes like adsorption, desorption and diffusion are included. The hierarchy of equation is truncated by using mean …-field (m,n) closures. Equilibrium properties are analyzed. In particular, adsorption isotherms as a function of the nearest …

Adsorption, desorption and diffusion of extended objects on a square lattice

Budinski-Petković, Lj; Tošić, T - In: Physica A: Statistical Mechanics and its Applications 329 (2003) 3, pp. 350-356

Kinetics of the adsorption–desorption process with diffusional relaxation is studied by Monte-Carlo simulations on a … square lattice. At each Monte-Carlo step three independent processes proceeding in parallel are attempted: adsorption …, desorption and diffusion. The time is measured by the number of adsorption attempts per lattice site and the kinetics of the …
