Multiphysics Modeling with Finite Element Methods by William B J Zimmerman Pdf

Finite element methods for approximating partial differential equations that arise in science and engineering analysis find widespread application. Numerical analysis tools make the solutions of coupled physics, mechanics, chemistry, and even biology accessible to the novice modeler. Nevertheless, modelers must be aware of the limitations and difficulties in developing numerical models that faithfully represent the system they are modeling. This textbook introduces the intellectual framework for modeling with Comsol Multiphysics, a package which has unique features in representing multiply linked domains with complex geometry, highly coupled and nonlinear equation systems, and arbitrarily complicated boundary, auxiliary, and initial conditions. But with this modeling power comes great opportunities and great perils. Progressively, in the first part of the book the novice modeler develops an understanding of how to build up complicated models piecemeal and test them modularly. The second part of the book introduces advanced analysis techniques. The final part of the book deals with case studies in a broad range of application areas including nonlinear pattern formation, thin film dynamics and heterogeneous catalysis, composite and effective media for heat, mass, conductivity, and dispersion, population balances, tomography, multiphase flow, electrokinetic, microfluidic networks, plasma dynamics, and corrosion chemistry. As a revision of Process Modeling and Simulation with Finite Element Methods, this book uses the very latest features of Comsol Multiphysics. There are new case studies on multiphase flow with phase change, plasma dynamics, electromagnetohydrodynamics, microfluidic mixing, and corrosion. In addition, major improvements to the level set method for multiphase flow to ensure phase conservation is introduced. More information about COMSOL can be found here.

Advanced Computational Approaches for Water Treatment by Krunal M Gangawane,Madhuresh Dwivedi,Praveen Ghodke Pdf

A rapid growth in global industrialization and population has triggered intense environmental pollution that has led to a water crisis, resulting in the decay in the quality of human life and economic losses. Novel water purification techniques are expected to alleviate this challenge. Recently, various water purification techniques, along with different computational techniques, have been developed. For instance, water purification techniques, such as electromagnetic water purification, solute-surface interactions in water, use of micro-magnetofluidic devices, UV-led water purification, and use of membranes can be thoroughly investigated by using a range of computation techniques, such as molecular dynamics, the lattice Boltzmann method, and the Navier-Stokes method-based solver. Advanced Computational Approaches for Water Treatment: Applications in Food and Chemical Engineering, presents these different numerical techniques and traditional modeling and simulation approaches to elaborate on and explain the various water purification techniques. Features: Serves as a dedicated reference for this emerging topic Discusses state of the art developments in advanced computational techniques for water purification Brings together diverse experience in this field in one reference text Provides a roadmap for future developments in the area This book is primarily intended for chemical engineers, hydrologists, water resource managers, civil engineers, environmental engineers, food scientists and food engineers interested in understanding the numerical approaches for different water purification techniques, such as membrane, sedimentation, filtration, micromagnetofluidic device, and ozone/UV, among others.

High temperature polymer electrolyte membrane fuel cells by Christian Siegel Pdf

A three-dimensional computational fluid dynamics model of a high temperature polymer electrolyte membrane fuel cell, employing a high temperature stable polybenzimidazole membrane electrode assembly doped with phosphoric acid, was developed and implemented using a commercially available finite element software. Three types of flow-fields were modeled and simulated. Selected simulation results at reference operating conditions were compared to the performance curves and to segmented solid-phase temperature and current density measurements. For the segmented measurements, an inhouse developed prototype cell was designed and manufactured. The segmented cell was successfully operated and the solid-phase temperature and the current density distribution were recorded, evaluated, and discussed. Sequentially scanned segmented electrochemical impedance spectroscopy measurements were performed to qualitatively support the observed trends. These measurements were used to identify and determine the causes of the inhomogeneous current density distributions. An equivalent circuit model was developed, the obtained spectra were analyzed, and the model parameters discussed. This work helps to provide a better understanding of the internal behaviour of a running high temperature polymer electrolyte membrane fuel cell and presents valuable data for modeling and simulation. For large fuel cells and complete fuel cell stacks in particular, well designed anode and cathode inlet and outlet sections are expected to aid in achieving flatter quantities distributions and in preventing hot spots over the membrane electrode assembly area, and to develop proper start-up, shut-down, and tempering concepts.
