Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...

COMSOL Multiphysics has been used to validate and check the design of a header transporting ammonia gases released from pressure safety valves (PSVs) to the tip of the flare. The header is part of a dedicated flaring system to contain emissions from ammonia storage tanks. The two main challenges are the low relief pressure and high capacity of the system. Another difficulty is the high relief ...

The hydraulic flocculates are employed in water treatment plants (WTPs), but may present problems during the mixing stage reducing the efficiency of treatment. In this context modeling of a hydraulic flocculate using COMSOL and a 1:10 scale model of the Maringá-PR Brazil city WTP flocculate was done. The WTP flocculate is shown in figure 1 and the model illustrating the acrylic flocculate ...

In this model a three-dimensional heat transfer analysis was performed by using COMSOL Multiphysics\' Heat Transfer Module. The model is about the heating of a set of vials (Figure 1) in a current of hot air in the laminar regime. We used time dependent studies to predict the thermal behavior of the glass and to estimate the temperatures in the various points of the bottles at various times. ...

Multiphysics simulation has been used extensively in our research for fluid flow and heat transfer applications. Our projects include: simulation of fluid dynamics in an active liquid heat sink for CPU cooling, impeller design for a pipe flow generator with computational fluid dynamics (CFD), investment casting with plastic rapid prototype patterns, phase change materials with rapid prototyping ...
Analysis of the Characteristics of the Terahertz Communication Device by using the COMSOL RF Module and its Complement
Tokyo Metropolitan University, Hachioji, Tokyo, Japan
We present simulated examples of analyzing characteristics of terahertz communication devices by using the COMSOL RF module. Especially, we propose a coupled analysis method, which has a mutually complementary relationship between the numerical analysis in the COMSOL and an additional theoretical analysis. In this work, applying this analysis for characterizing of radiation, transmittance and ...
Interaction between Light Wave and Asymmetric Metal/Insulator/Metal (MM) Structure Coupled with Subwavelength Holes at Optical Fiber Apex
Osaka University, Suita, Osaka, Japan
Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of asymmetric metal/insulator/metal (MIM) layers coupled with subwavelength holes. Behavior of surface plasmon ...

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 dug few meters deep in soil. Unlike BHEs which benefit from the relatively stable temperature of deep soil, ...

A Proton Exchange Membrane Fuel Cell (PEMFC) is an electrochemical device, which converts a part of heat from the formation of water into electricity. Each cell has a Membrane-Electrode Assembly (MEA) which is placed between two electrically conducting plates having gas flow channels. An MEA is made of a solid proton-conducting electrolyte sandwiched between two electrodes (anode and cathode). ...

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery such that the mass transport of glucose around all the micro-electrodes can be improved and hence output ...
