Solute mass transfer is considered from the outside to the inside of a circulating drop in the context of liquid-liquid extraction. Specifically an internal problem is treated with resistance to mass transfer dominated by ...

Numerical simulations of mass transfer are performed for a circulating liquid drop with applications in liquid–liquid extraction. Simulation parameters are chosen for a multi-component ternary system acetone–methanol–benzene. ...

Macroscopic coefficients that are needed to complete porous media models, such as the thermal dispersion and the interfacial heat transfer, are in general calculated under thermally and hydrodynamically fully developed ...

This work investigated numerical methods in the solution of mathematical models of fixed-bed reactors. For the reactors modeling and simulation, two numerical methods were used: sequencing method (SM) and finite volume ...

El presente artículo describe el método Petrov-Galerkin en contracorriente (SUPG) como técnica de estabilización de las solucio- nes por elementos finitos de la ecuación diferencial de difusión –advección- reacción. En la ...

El presente trabajo analiza y compara los problemas numéricos derivados al modelar problemas altamente convectivos empleando diversos métodos espectrales y el método Streamline Petrov-Galerkin de elementos finitos (SUPG). ...

Electrolyte viscosity plays an important role in ion transport. Here we study the effects of high viscosity variations in thin-layer electrochemical deposition (ECD) under constant-current conditions through experimental ...

Laminar forced convection inside tubes of various cross-section shapes is of interest in the design of a low Reynolds number heat exchanger apparatus. Heat transfer to thermally developing, hydrodynamically developed forced ...
