Parameterization and Validation of a 2D, Transient, Two-Phase MEA Model Capable of Simulating EIS

M. Eppler¹, M. Hanauer¹, C. Gerling¹, U. Berner¹, M. Eikerling²
¹Robert Bosch GmbH, Gerlingen, Germany
²Forschungszentrum Jülich, IEK-13: Theory & Comp. of Energy Materials, Germany

Proton exchange membrane fuel cells (PEMFCs) are promising energy converters, offering both sustainability and efficiency. Achieving optimal performance, however, requires a deep understanding of the underlying cause-effect relationships within the functional layers. One effective ... Read More

Electrical field effect on CO2 absorption and chemisorption in a rectangular bubble column by COMSOL

Raman Kumar Singh¹, Prakash Chandra Ghosh¹, Venkatasailanathan Ramadesigan¹
¹Department of Energy Science and Engineering, IIT Bombay, Mumbai, India

The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ... Read More

A Multiphase Model to Analyze Transport Phenomena In Convective Drying

S. Curcio, and M. Aversa
Department of Engineering Modelling, University of Calabria, Rende, Italy

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... Read More

Development of a Multiphase, Multispecies Droplet Evaporation Model for Optimization of Desiccation Preservation Techniques

A. Sinkevich[1], S. Bhowmick [1], M. Raessi[1]
[1]University of Massachusetts Dartmouth, North Dartmouth, MA, USA

Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... Read More

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Read More

Geologic Carbon Storage: Implications of Two-Phase Flow on Injection-Induced Stress on Faults

S. Prasun [1], S. Kim [2], S. A. Hosseini [3],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Department of Civil Engineering University of Nebraska - Lincoln, Omaha, NE, USA
[3] Bureau of Economic Geology, University of Texas - Austin, Austin, TX, USA

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... Read More

Study of 3D Focused Droplet Generation in a 2D Flow Focusing Microfluidic Geometry

A. Mohan [1], P. Gupta [2], T. Saiyed [2], Dr. A. Prabhakar [1],
[1] Indian Institute of Technology Madras, Chennai, Tamil Nadu, India
[2] Centre for Cellular and Molecular Platforms, Bangalore, Karnataka, India

We have chosen droplet-based microfluidics as a platform for single cell analysis using the encapsulation technique. For this, we study the water in oil droplets formation inside a 2D microfluidic flow focusing geometry designed. We have performed Computational Fluid Dynamics (CFD) ... Read More

Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

T. Gulati[1], A. Datta[1]
[1]Department of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport ... Read More

A Multiphase Porous Medium Transport Model with Distributed Sublimation Front to Simulate Vacuum Freeze Drying

A. Warning[1], J. M. R. Arquiza[1], A. K. Datta[1]
[1]Cornell University, Ithaca, NY, USA

A continuum, porous medium formulation with non-equilibrium sublimation was developed and validated for freeze drying without and with uniform microwave volumetric heating. The model incorporates the effect of Knudsen flow at low pressure and low permeability freeze drying. The ... Read More

CFD Investigation of Cross Bubbly Flow through a Bubble Column with Rectangular Geometry

N. M. Musa [1], D. Kuvshinov [1], P. Rubini [1],
[1] The University of Hull, Hull, East Yorkshire, United Kingdom

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... Read More
