Using a Level-Set Model to Estimate Dwell Time in a Vacuum Dewatering Process for Paper

K. Rezk[1]
[1]Department of Energy, Environmental and Building Technology, Karlstad University, Kronoparken, Sweden

Water removal during paper manufacturing is an intensive energy process. The dewatering process generally consists of four stages in which the first three stages, water is removed mechanically through vacuum pulses and pressing.The fourth stage involve thermal drying. The vacuum ... Mehr lesen

Coupling Forced Convection in Air Gaps with Heat and Moisture Transfer inside Constructions

M. Bianchi Janetti[1], F. Ochs[1]
[1]University of Innsbruck, Innsbruck, Austria

Introduction: The simulation of coupled heat and moisture transfer in constructions is becoming even more important in the last years. COMSOL Multiphysics represents a powerful tool for this kind of simulations as shown in [1,2,3], although applications in this area are still rare. For ... Mehr lesen

Design of Solar Thermal Dryers for 24-hour Food Drying Processes

F. S. Alleyne [1], R. R. Milczarek [1],
[1] Healthy Processed Foods Research Unit, U.S. Department of Agriculture, Albany, CA, USA

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... Mehr lesen

Modeling the Behavior of a Polymer Electrolyte Membrane within a Fuel Cell Using COMSOL

S. Beharry[1]
[1]University of the West Indies, St. Augustine, Trinidad and Tobago

One viable alternative to non-renewable fossil fuels is the fuel cell. A special class of FC i.e. Proton Exchange Membrane Fuel Cell (PEMFC) has been investigated during the present study. Membrane is a very important part of a PEMFC as most ohmic losses occurs here and limits the ... Mehr lesen

Using COMSOL for the Transport Modelling of Some Special Cases in a Bentonite Buffer in a Final Repository for Spent Nuclear Fuel

M. Olin[1], V-M. Pulkkanen[1], A. Seppälä[1], T. Saario[1], A. Itälä[1], M. Tanhua-Tyrkkö[1], and M. Liukkonen[1]

[1]VTT, Technical Research Centre of Finland, Espoo, Finland

The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics® is used in modelling the Thermal (T), Hydrological (H), Mechanical (M) and Chemical (C) phenomena and processes taking place in a bentonite buffer. Special ...

Direct Pore-scale Modeling of Two-phase Flow Through Natural Media

I. Bogdanov, J. Kpahou, and A. Kamp
Open and Experimental Centre for Heavy Oil (CHLOE)
University of Pau
Pau, France

Direct numerical simulation of single- and two-phase flow in real pore systems is addressed in our paper. The X–ray computed micro-tomography technique has been applied first to reconstruct in details a real pore space of a subcentimetric sample. Making use of dedicated software (ScanIP) ... Mehr lesen

Earth Pressure as a Boundary Condition to Bridge Piers and Abutments

M. Quinn[1], D. Whitlow[1], O.D.S. Taylor[1], M.H. McKenna[1]
[1] Engineer Resource and Development Center, United States Army Corps of Engineers, Vicksburg, MS, USA

Bridge piers and abutments makeup the bridge substructure and transmit loads from the superstructure to the bridge foundation material (Figure 1). The bridge abutment serves three purposes: to provide vertical support to the bridge superstructure where the bridge ends, to connect the ... Mehr lesen

Numerical Modeling of Powder Flow During Coaxial Laser Direct Metal Deposition: Comparison Between Ti-6Al-4V Alloy and 316L Stainless Steel

[1]Université de Bretagne-Sud/UEB-LIMATB, Lorient, France
[2]PIMM, Arts et Métiers ParisTech, Paris, France

This paper presents a 3D numerical model to predict the whole process of coaxial powder flow, including the particle stream flow in and below the nozzle and also the laser-particle interaction process. The Particle Tracing Module of COMSOL Multiphysics is used to solve the coupled ... Mehr lesen

Multi-Objective Optimization of a Strip-Fin Microchannel Heatsink: Integrating COMSOL Multiphysics with modeFRONTIER

A. Clarich, R. Russo, and N. Fateh
Esteco North America, Miami, FL, USA

For this work the multi-objective design environment modeFRONTIER was integrated with COMSOL, bringing the advantages of multi-objective optimization to multiphysics simulations. Practically any commercial analysis tool (such as COMSOL) or in-house code can be integrated within ... Mehr lesen

Inclusive Routine of the Soil Surface Energy Balance in COMSOL Multiphysics®

M. Bortoloni[1], M. Bottarelli[2], Y. Su[3]
[1]Department of Engineering, University of Ferrara, Este, Italy
[2]Department of Architecture, University of Ferrara, Este, Italy
[3]Faculty of Engineering, University of Nottingham, Nottingham, UK

In ground-coupled heat pumps (GCHPs) the coupling between heat pumps and ground occurs by means of ground heat exchangers, that can be installed vertically inside boreholes (BHEs) or horizontally (HGHEs). In the horizontal installation, the heat exchangers are placed in shallow trenches ... Mehr lesen
