Intervertebral discs (IVD) are fibro-cartilages situated between vertebrae providing their joint flexibility. They play a major role in the transmission and absorption of load through the spine. The disc can undergo progressive structural and quantitative changes in its composition and morphology related to mechanical load applied to the spine which can lead to disc degeneration; this disease is ...

At the 2006 Winter Olympics, the jump length difference between first and second place was only 5cm. This illustrates why ski jumpers are constantly tinkering with their posture in order to gain even the smallest of advantages. Experiments such as those shown in Figures 1 and 2 (b), conducted with ski jumpers in large-scale wind tunnels showed that even small changes in position can lead to ...
采用有限元模拟软件 COMSOL Multiphysics® 对液封直拉法（LEC）生长锑化镓（GaSb）晶体的物理过程进行计算机建模。模拟分析了晶体旋转与坩埚旋转工艺对 GaSb 固-液界面形貌的影响。模拟结果表明，晶体旋转与坩埚旋转工艺将导致强烈的熔体强制对流，并进一步影响固液相变物理过程。上述工艺将分别具有促使凸向熔体的固液界面曲率减小和增大的作用，且同等转速条件下，坩埚旋转对固液界面形貌影响更大。基于上述模拟结果优化了实验中坩埚转速、晶体转速参数，最终获得了近似“平面”形貌的固液界面，由此获得了低位错密度的 GaSb 单晶。

In this study the flow through a tube filled with highly porous aluminium foam of three different pore sizes is analysed using COMSOL Multiphysics® CFD Module and compared to experimentally determined pressure drop data. Analyzing the flow through an array of pores allow the deduction of characteristic flow parameters (permeability and form drag coefficient) that are utilized in a 2D ...

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability effects demands pore-level investigations which are still limited. In this paper, COMSOL Multiphysics® software ...

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of the electric field. DEP is caused by polarization of the DNA particle. Two different electrode geometries ...

Conventional polarization maintaining fiber is constructed using a pair of borosilicate rods on either side of the fiber core. Current manufacturing processes prohibit the construction of fibers with the required accuracy needed for applications requiring precision birefringence. Through the use of COMSOL, this paper describes simulated results of fiber with a mutually orthogonal secondary set ...

The quality of coatings obtained by means of thermal spraying depends strongly on the mechanism of the interaction between the molten droplets and the surface to be covered. The aim of the present study is to simulate the impact of a droplet onto a substrate, in order to have a good understanding of the dynamics of droplets impact. In this study, the process of droplet spreading is described; ...

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate deep laminar flow, a condition with very poor heat transfer rates and high pressure losses involving a ...
