The effects of laminar mixing on reaction fronts and patterns

A wide variety of dynamical processes are influenced by some sort of reaction. In its most general sense, a “reaction” is when some species A changes into some other species B during a process, possibly via an interaction with other species. The most obvious example is a chemical reaction, when two or more reactants interact to form a third product, e.g., A + B  C or A + B  2A. Combustion is ...

Non-Planar Fronts in Boussinesq Reactive Flows

We consider the reactive Boussinesq equations in a slanted cylinder, with zero stress boundary conditions and arbitrary Rayleigh number. We show that the equations have non-planar traveling front solutions that propagate at a constant speed. We also establish uniform upper bounds on the burning rate and the flow velocity for general front-like initial data for the Cauchy problem.

Evaluation of the performance of conventional and baffled horizontal subsurface constructed wetland in the removal of Reactive Red 198

Background and Objective: Reactive Red 198 is a mono azo dye widely used in the textile industry of Iran. The toxicity of reactive dyes is higher than other dyes and causes disorders such as irritation, cancer and mutation in humans. The overall objective of this study was to determine the efficiency of a Constructed Wetland pilot system with conventional and baffled horizontal subsurface flow ...
