Fully Coupled FEM Modeling of the Swelling Behavior of Human Intervertebral Disc in Response to a Change in Chemical Environment

G. K. Mistri[1], K. J. Suthar[2]
[1]Department of Mechanical and Industrial Engineering, University of Illinois at Chicago, Chicago, IL, USA
[2]Advanced Photon Source, Argonne National Laboratory, Argonne, IL, USA

The swelling behavior of human intervertebral disc is strongly influenced by chemical changes in the surrounding environment. Swelling of IVD is governed by various physical phenomena, including chemical and electric potential based transport, electrical charge balance, and swelling due ... Per saperne di più

[3]Department of Mechanical Engineering, Western Michigan University, Kalamazoo, MI, USA

The pH-sensitive hydrogels are responsive to the pH of surrounding solution, which often resemble to biomaterials. Recently, pH-sensitive hydrogels are widely used in various devices as sensing media. We present the simulation of swelling characteristic of 3D-arbitarary-geometry, pH ... Per saperne di più

Equation Based Heat and Mass Transfer in Porous Media

S. Pemberton[1], K. Ekici[1], R. Arimilli[1]
[1]The University of Tennessee, Knoxville, TN, USA

Perspiration during intense physical activity is an essential part of human thermoregulation. Clothing affects the cooling rate of the body. Heat and water vapor are coupled through evaporation and transported through the fabric. A model of the above system was developed for fabrics of ... Per saperne di più

3D Hydrogeological Modeling - From a Theoretical 2D Model through a Medium Scale Application up to a Challenge: Simulations at Basin Scale

E. Cavalli[1], R. Simonetti[1], M. Gorla[1], N. Ceresa[1]
[1]CAP Holding, Milan, Italy

An alluvial aquifer system has probably conceived as a numerical modeling hell. We have chosen COMSOL Multiphysics® for two reasons: 1) FEM methods allow to use complex geometries; 2) multiphysics simulation permits to run a single model with all phenomena. We built a section with these ... Per saperne di più

Comparison Between Flow Simulations and Foam Experiments in Porous Media

R.R. Thorat[1], H. Bruining[1]
[1]Petroleum Engineering, CiTG, TU Delft, Delft, The Netherlands

Recovery of oil by gas injection is usually inefficient due to the low viscosity of the gas, which results in bypassing of the oil. By adding surfactant solutions it is possible to get in-situ foam formation. Foam has a much higher “viscosity” and hence does not bypass the oil, leading ... Per saperne di più

Modelling of the Wool Textile Finishing Processes

M. Giansetti[1], A. Pezzin[1], S. Sicardi[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are ... Per saperne di più

Void Shape Evolution of Silicon Simulation in COMSOL Multiphysics®
