The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. Relative ...

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based fluid transport equations for various phases; near-equilibrium equation governing phase change from liquid ...

Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a defined number of holes on its top and bottom lines, maintaining semi-captive air between itself and the gun. The ...

Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating particle system including damping in order to damp out the time derivatives and attain a stationary solution ...

The feasibility of water cooling is investigated for a solid target which is integrated as the inner conductor in a magnetic horn for secondary particle focusing (pi; K) as used in conventional neutrino beam accelerator experiment. A simple axi-symmetric thermal model calculated in COMSOL is used to obtain the temperature distribution inside the target for different values of h; power beam and ...
Modeling of Nonlinear and Non-stationary Multi-vortex Behavior of Electronic Crystal in Restricted Gemoetries of Nano Junctions
T. Yi, Y. Luo, and S. Brazovskii
Electronic Crystals are common forms of organization of charge in solids. They appear widely from nano-structure semiconductors to synthetic organic conductors. Charge density wave, the best treated kind of electronic crystal, can readjust its elementary units by creation of topological defect or vortex. Experimental accesses to these phenomena came from nano-junctions, scanning tunneling ...

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main energy transfer mechanism. In Newtonian fluids dynamic behaviour is described by the Navier-Stokes ...
COMSOL Multiphysics Modelling for Measurement Device of Electrical Resistivity in Laboratory Test Cell
C. Rémi, M. Bergeron, and S. Moreau
Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many physical parameters and no single relationship with volumetric water content was yet established for Municipal ...

Introduction of silicone hydrogel contact lens materials provided products of unprecedented capability to deliver oxygen to the eye during wear. One additional material characteristic of interest is the material’s permeability to ions. This paper discusses descriptive tools and optimization of an impedance method of characterizing ion permeability. A physical model of conductive paper with ...
