Thermo-fluid Dynamics Modelling of Hydrogen Absorption and Desorption in a LaNi4.8Al0.2 Hydride Bed
A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... Read More
Chemical Reactions in a Microfluidic T-Sensor: Numerical Comparison of 2D and 3D Models
In recent years lab-on-microchip technology has become a powerful tool for micro-scale analysis of biochemical processes. In the studied system the overall process consists of transport, convection, diffusion, reaction and adsorption processes. Two compounds A and B, contained in a ... Read More
