Preferential sorption versus preferential permeability in pervaporation [PDF]
, 1985 Transport of liquids by pervaporation takes place by a solution—diffusion mechanism. In order to investigate the “solution part” of this transport model, preferential sorption has been compared with preferential permeability.

Hydrogen-enriched nonpremixed jet flames: Effects of preferential diffusion
International Journal of Hydrogen Energy, 2013 Influence of preferential diffusion on the dynamics of hydrogen and syngas nonpremixed impinging jet flames was studied using direct numerical simulation and flamelet generated manifolds based on detailed chemical kinetics. The results presented in this study were obtained from a uniform Cartesian grid with 768 × 768 × 768 points.

Accumulation is late and brief in preferential choice [PDF]
, 2020 Preferential choices are often explained using models within the evidence accumulation framework: value drives the drift rate at which evidence is accumulated until a threshold is reached and an option is chosen. Although rarely stated explicitly, almost
