چکیده
One of the major challenges in design micro-devices, when very fast reactions are carried out, is to overcome limited performance due poor mixing efficiency reactants. Here, we report a holistic analysis reactants and reaction rate liquid phase flow micro-reactors with curved geometries. In this sense, mathematical model that accounts for momentum mass conservation equations, together species transport chemical under isothermal conditions, has been developed using computational fluid dynamics techniques (CFD). To validate predictive model, four micro-reactor geometries different radius length (straight reactor, two types serpentines an Archimedean spiral) have evaluated. Simulated results proved promoted through formation Dean vortices as consequence reduction curvature at same time extension curve. Thus, overall improved because limitations minimized process kinetics greatly enhanced. Accordingly, spiral reported best by reducing half required obtain 95 % conversion compared straight reactor. findings confirmed experimental between aqueous ammonium hypochlorite ions. Very good agreement simulated achieved error lower than 10 %. Therefore, robust herein novel valuable tool assist optimum fluid-phase applications.

Numerical study of flow of labyrinth weir with triangular and curved plan form using Fluent software
Labyrinth weirs have not a straight crest in the perpendicular direction to the flow. The plan view of the weir consists of multiple and broken linear crests that cause the increase of its effective length. The advantages of this type of weirs are higher discharge capacity, easy aeration as well as low fluctuations of water surface at the weir upstream. This paper deals with the simulation of t...

متن کاملNumerical gradient flow discretization of viscous thin films on curved geometries
The evolution of a viscous thin film on a curved geometry is numerically approximated based on the natural time discretization of the underlying gradient flow. This discretization leads to a variational problem to be solved at each time step, which reflects the balance between the decay of the free (gravitational and surface) energy and the viscous dissipation. Both dissipation and energy are d...
