Simulation of Spiral-Tube Heat Exchangers in COMSOL Multiphysics® Software

K. O. Lund [1], S. M. Lord [2],
[1] Kurt Lund Consulting (COMSOL Certified Consultant), Del Mar, CA, USA
[2] SML Associates, Encinitas, CA, USA

A frequently occurring geometry for heat exchangers is that of a long tube wound into a helix or spiral around a core volume. There is to be heat exchange between the tube and the gases (or solids) in the core. However, the length scales of these two parts of the geometry are very ... En savoir plus

Combining Multiphysics Modeling and Solution Thermodynamics Using M4Dlib, an External Library

T. Marin-Alvarado [1],
[1] M4Dynamics, Toronto, ON, Canada

An external library, M4Dlib [1], has been developed to solve multiphysics problems coupled to solution thermodynamics. This approach extends the local equilibrium concept[2] to multiphysics modeling by incorporating a full Gibbs energy minimization routine at each numerical node to ... En savoir plus

Development of a Thermo-Hydro-Geochemical Model for Low-Temperature Geoexchange Applications

F. Eppner [1], P. Pasquier [1], P. Baudron [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... En savoir plus

Scraping Non-Newtonian Power-Law Paint

C. R. Meyer [1], J. R. Rice [1],
[1] Harvard University, Cambridge, MA, USA

A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. ... En savoir plus

Simulation of Vector Mode Grating Coupler Interfaces for Integrated Optics

C. T. Nadovich [1],
[1] Lafayette College, Easton, PA, USA

The use of grating couplers to couple conventionally phased and polarized light near vertically in and out of optical slab or film waveguides [1] represents an attractive method to interface optical fiber to photonic ICs. Previously developed grating coupler designs use transversely ... En savoir plus

PDT Study Using a Model Incorporating Initial Oxygen Concentration and Blood Flow Increase

R. Penjweini[1], T. C. Zhu[1],
[1] Department of Radiation Oncology, University of Pennsylvania, Philadelphia, PA, USA

Introduction: Type II photodynamic therapy (PDT) is an experimental modality for cancer treatment based on the combined action of a photosensitizing drug (photosensitizer), a special wavelength of light and singlet oxygen (1O2) generation; the cell killing is caused by the reaction of ...

Plasma Scaling Leads the Transition from 2D to True 3D Models

J. Brcka [1],
[1] Tokyo Electron U.S. Holdings, Inc., Austin, TX, USA

Introduction: In inductively coupled plasma (ICP) systems the inductive antenna is coupled to the excited plasma inside the low pressure gas reactor. A multi-ICP system can be used for increased area processing and provide additional variables for controlling the plasma. However, ... En savoir plus

Development of a Thermal Model Using COMSOL Multiphysics® Software

A. Oukaira [1], A. Lakhssassi [1],
[1] Department of Computer Science, Université du Québec en Outaouais à Hull, Gatineau, QC, Canada

The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... En savoir plus

Thermal Stresses in Functionally Graded Metal-Ceramic Plates

E. Gutierrez-Miravete [1],
[1] Rensselaer at Hartford, Hartford, CT, USA

Functionally graded composite materials are attracting interest among design engineers since structural component properties can be designed and customized into finished parts through processing. The controlled variable is the concentration of reinforcing particles at various points ... En savoir plus

Transport Phenomena in the Conversion of an Anaerobic Landfill into an Aerobic Landfill

H. Omar [1], S. Rohani [1],
[1] University of Western Ontario, London, ON, Canada

The world’s landfills are beginning to fill up due to the growing human population. Landfills require land and there will come a time when there will be no land to be used for landfills. A solution that is gaining attraction is the conversion of traditional “dry-tomb” landfills (used for ... En savoir plus
