Deformable image registration is a form of medical image processing that can provide insights into the development of phenomenon and variation in normal anatomical structure over time. Prior to post-operative pleural photodynamic therapy (PDT), a series of CT scans of lungs will be acquired. During PDT treatment, an infrared navigation system is used to contour the lungs and provide real-time ...

The production of polymer fibers is done by drawing raw material (preform) in a vertical cylindrical furnace whose heated walls radiantly heat the preform. The wall temperatures are very high and the dominant heat transfer to the fiber is by radiation with little effect from the convective flow of gas in the furnace. In contrast, for polymer fibers the convection contribution is large, and ...

In this research, we performed multiple COMSOL Multiphysics® simulations. We analyzed the dispersion curves of waves in a LAMB wave pressure sensor; simulated a thin metal film in a microbolometer and observed the resulting stress; investigated the thermal behavior of an acoustic wave microbolometer; and modeled the fluid-structure interaction (FSI) for piezoelectric-based energy harvesting from ...

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 to enhanced oil recovery. In this context, the foam propagation is studied experimentally and theoretically. ...

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of storage is based on a clay formation with low permeability, homogeneity and continuity (i.e Callovo-Oxfordian ...

The first aim of our work is to create a hydro-mechanical model (HM) of unsaturated fluid flow in bentonite-sand mixture (BSM) MX-80. The second aim is to validate and calibrate the developed model by using the data from a laboratory infiltration test of BSM. The used multi-physics model combines Richards type unsaturated flow with diffusive vapour flow and (nonlinear) elastic response of the ...

We theoretically studied the microwave coplanar line of different geometry based on MgO substrate with a thin (30 nm) ferroelectric layer under the external electric field using the environment of 3D modeling in COMSOL Multiphysics®, RF Module, Frequency Domain. Frequency dependence of delay line coefficient S21 was obtained. Sizes of the microstrip and the gap between the strip and the ground ...

The study of interaction of fluid with matter assumes great significance for most engineering applications. The flow can be either turbulent or laminar, and different types of interactions arise out of these flow. In the introductory undergraduate course of fluid mechanics, a typical demonstration for these interactions is the Reynolds pipe flow experiment. Instabilities of various types like ...

We, Sumitomo Heavy Industries, Ltd. have been developing a microwave ion source since 2011. The design of the chamber is important to generate plasma efficiently. The plasma chamber was designed with the COMSOL Multiphysics RF module, and reported the results at this conference last year. In order to improve the reflective characteristic further, we redesigned the plasma chamber with the RF ...

Thermally responsive microgel Poly (N-isopropylacrylamide), particles are embedded with iron oxide nanobeads creating magneto-thermally responsive microparticles (MTMs). The magnetic losses in the nanobeads activate the PNIPAM by heating it up to its lower critical solution temperature (LCST), which is approximately 32°C. The COMSOL Multiphysics® software with Heat Transfer Module is used to ...
