Two-phase Flow Calculations in Pore Unit Cells Implementing Mixed FEM/Lattice-Boltzmann Simulators

E. D. Skouras [1][2], A. N. Kalarakis [2], M. S. Valavanides [3], V. N. Burganos [1],
[1] Foundation for Research and Technology, Hellas/Institute of Chemical Engineering Sciences, Patras, Greece
[2] Dept of Mechanical Engineering, TEI of Western Greece, Patras, Greece
[3] Dept of Civil Engineering, Applied Mechanics Laboratory, TEI of Athens, Athens, Greece

In general, macroscopic two-phase flow in porous media is a mixture of connected and disconnected oil flow. The latter is expressed as ganglion dynamics and drop traffic flow, patterns observed experimentally in pore network models [1,2] and real porous media [3,4]. This characteristic ... Read More

Effects of Flow and Diffusion on Blood Coagulation in Platelet Poor Plasma: a Two-way Coupling Between Hemodynamics and Biochemistry

D. Magnabosco[1,2], H. van Ooijen[2], B. Bakker[2], R. van den Ham[2]
[1]Politecnico di Milano, Milan, Italy
[2]Philips Research, Eindhoven, The Netherlands

Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and ... Read More

Hydrodynamics of Lake Victoria: Vertically Integrated Flow Models in COMSOL Multiphysics® Software new

S. Paul[1], R. Thunvik[1], D. D. Walakira[2], J. Mango[2], J. Oppelstrup[3], R. Wait[4]
[1]The Royal Institute of Technology, Stockholm, Sweden
[2]Makerere University, Kampala, Uganda

[1] NASA Marshall Space Flight Center, Huntsville, AL, USA

Introduction: Developments intended to improve system efficiency and reliability for water and carbon dioxide separation systems to be used on crewed vehicles combine sub-scale systems testing and multi-physics simulations. This paper describes the development of simulations in COMSOL ... Read More

Copper Electrochemical Polishing Optimisation

A. Pérez Rodríguez [1], L. Marques Antunes Ferreira [1],
[1] CERN, Geneva, Switzerland

A new electrochemical polishing facility will be built at CERN to process copper radiofrequency structures and this in the framework of the Future Circular Collider study. This polishing installation will be designed and assembled so that the necessary working conditions to achieve the ... Read More

On The Purification Of Waste Waters Using Multi-Bore Filters: Simulation Of A Long-Term Filtration Stage

I. Borsi
Dipartimento di Matematica U. Dini, Universita' di Firenze, Italy

We present the progress of the simulation activity we are carrying out within the PURIFAST LIFE+ project. We first present the model we formulated to describe the macroscopic effects of the filtration process taking place in a multi-bore filter, focusing on the fouling phenomenon. In ... Read More

External Field Induced Flow Patterns in Microscale Multiphase Flows

D. Bandyopadhyay[1], A. Sharma[1], S. Timung[1], V. Tiwari[1], T. K. Mandal[1]
[1]Department of Chemical Engineering, Indian Institute of Technology Guwahati, Guwahati, Assam, India

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on ... Read More

Numerical Analysis of the Thermal Resistance of a Multi-Layer Reflective Insulation Material Enclosed by Cavities under Varied Angles

R.S. Pelzers[1], A.W.M. van Schijndel[2]
[1]Former student Building Physics, Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands
[2]Chair Building Physics, Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands

A numerical analysis on the thermal performance of a sample, consisting of two cavities surrounding a Multi-Layer Reflective Insulation (MLRI) material, under various angles and for downward and upward heat flows was performed. The sample reached high thermal resistance values when ... Read More

Reducing Solar Heat Gain from Inclined Buildings’ Roof by Using Radiant Barrier System

S. Ebrahim[1], A. Alshayji[1]
[1]Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait City, Kuwait

The study produced a simulated model of natural convection in an inclined rectangular channel open ended with different locations of radiant barrier (RB) along the channel thickness(S). The upper plate is heated by various uniform constant heat fluxes while the inner surface of the lower ... Read More

A Black-Oil Model for Primary and Secondary Oil-Recovery in Stratified Petroleum Reservoirs
