Consulta en la Biblioteca ETSI Industriales (Riunet), [EN] This Master Thesis has three parts of study, and each one has its own aim. In all three, the influence of ultrasound is indispensable. Multiple parts of the phenomenon are investigated. First of all, the ultrasound will be introduced in the epoxidation reaction. As the effects of ultrasound in organic phase-reactions were mentioned in section 1.1 (―Motivation‖), the followed aim in this part is to achieve a better final conversion of double bonds, since the ultrasound (cavitation) is expected to have a positive effect on the speed of the epoxidation reaction in the organic phase.

A new unstructured mesh coastal water and air quality model has been developed that includes species transport, nonlinear decay, by-product formation, and mass-exchange between sea and atmosphere. The model has been programmed with a graphical user interface and is applicable to coastal seawater, lakes, and rivers. Focused on species conversion and interaction with the atmosphere, the water and air quality model follows a modular approach. It is a compatible module which simulates distributions based on fluid dynamic field data of underlying existing hydrodynamic and atmospheric simulations. Nonlinear and spline approximations of decay and growth kinetics, by-product formation, and joint sea-atmosphere simulation have been embedded. The Windows application software includes functions allowing error analysis concerning mesh and finite volume approximation. In this work, a submerged residual chlorine cooling water discharge and halogenated matter by-product formation has been simulated. An error analysis has been carried out by varying vertical meshing, time-steps and comparing results based on explicit and implicit finite volume approximation. The new model has been named 3D Simulation for Marine and Atmospheric Reactive Transport, in short 3D SMART. © 2013 Springer Science+Business Media Dordrecht.
