The historic Hofkeshuis in Almelo (The Netherlands) locates a unique work of art: three walls in the rear salon of the private house are covered with an 18th century series of painted wall hangings (Figure 1). The simple and similar pigmentation of the paintings, their original hanging, ... Read More

Simulations of Lateral Flow and Vertical Flow Microarray Assays for Point of Care Diagnostics new

G. E. Svedberg[1], L. Lama[1], J. Gantelius[1]
[1]Science for Life Laboratory, Stockholm, Sweden

Paper based lateral flow assays are widely used as point of care devices for disease diagnostics due to their low cost, short run time and ease of use. Binder molecules specific for certain molecular biomarkers of interest are typically deposited as dots or lines on paper strips, ... Read More

MEMS Acoustic Pixel new

A. Arevalo[1], I. G. Foulds[2]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2]The University of British Columbia, Vancouver, BC, Canada

A COMSOL Multiphysics® simulation was used to simulate the behavior of a micro-membrane (Acoustic Pixel) to be used as a potential acoustic transducer. The MEMS and Piezoelectric devices interfaces were used to simulate such transducer. A four-cantilever spring configuration is initially ... Read More

Improving Blood Flow Simulations Using Known Data new

T. Guerra[1], J. Tiago[2]
[1]Escola Superior de Tecnologia do Barreiro do Instituto Politécnico de Setúbal, Barreiro, Portugal
[2]Instituto Superior Técnico da Universidade de Lisboa, Lisboa, Portugal

Numerical simulations applied to blood flow together with the imaging processing advances are a powerful tool in the prevention and treatment of some diseases. The inclusion of real data in the numerical blood flow simulations allows the achievement of more realistic and accurate ... Read More

Thermal Natural Convection Simulations with COMSOL Multiphysics® in Comparison with Measurements new

H. van Halewijn[1]
[1]Fontys University of Applied Physics, Eindhoven, The Netherlands

In a laboratory setup a horizontal rod is heated on one side. By natural convection a stable temperature pattern is developed. Using the Nusselt formulation of the natural convection of cylindrical rods, the temperature distribution can be calculated. Only a good match of the simulations ... Read More

Finite Element Study of the Mass Transfer in Annular Reactor new

Y. M. S. El-Shazly[1], S. W. Eletriby[1]
[1]Alexandria University, Alexandria, Alexandria, Egypt.

The annular reactor is a very useful design to carry many chemical reactions. In this study, COMSOL Multiphysics® software was used to study the isothermal mass transfer from the inner side of the outer tube of the annular reactor in the range of 200 Read More

Heat Drain Device on Ultrasound Imaging Probe new

G. Vigna[1], L. Spicci[1]
[1]Esaote SPA, Florence, Italy

Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... Read More

The Hygro-Thermal Improvement of a Mounting System to Fasten Roof Workmen to Flat Roofs new

H. L. Schellen[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical ... Read More

Modeling of Ultrasonic Transducers and Ultrasonic Wave Propagation for Commercial Applications Using Finite Elements with Experimental Visualization of Waves for Validation new

D. R. Andrews[1]
[1]Cambridge Ultrasonics, Over, UK

Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... Read More

Two-dimensional Fluid Simulation of an RF Capacitively Coupled Ar/H2 Discharge new

L. Tong[1]
[1]Keisoku Engineering System Co., Ltd., Tokyo, Japan

Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the most ... Read More
