Effective diffusion coefficient including the Marangoni effect [PDF]
The Journal of Chemical Physics, 2018 Surface-active molecules supplied from a particle fixed at the water surface create a spatial gradient of the molecule concentration, resulting in Marangoni convection. Convective flow transports the molecules far from the particle, enhancing diffusion.

Fast Models for Predicting Pollutant Dispersion inside Urban Canopies
Atmosphere, 2023 A fast pollutant dispersion model for urban canopies is developed by coupling mean wind profiles to a parameterisation of turbulent diffusion and solving the time-dependent advection–diffusion equation.

Effective diffusivity of microswimmers in a crowded environment. [PDF]
Journal of Chemical Physics, 2018 The microalga Chlamydomonas Reinhardtii is used here as a model system to study the effect of complex environments on the swimming of micro-organisms. Its motion can be modeled by a run and tumble mechanism so that it describes a persistent random walk ...

Effective diffusivity of sulfuric acid in Antarctic ice cores [PDF]
Climate of the PastDeposition of sulfuric acid in ice cores is important both for understanding past volcanic activity and for synchronizing ice core timescales. Sulfuric acid has a low eutectic point, so it can potentially exist in liquid at grain boundaries and veins ...

Effective diffusions with intertwined structures
Matemática Contemporânea, 2023 Let p:N->M be a surjective map of smooth manifolds. We are concerned with singular perturbation problems associated to a pair of second order positive definite differential operators with no zero order terms, that are intertwined by p. We discuss the associated random perturbations of stochastic differential equations and present a number of ...
