When a dual probe heat pulse (DPHP) sensor is installed near the soil-atmosphere interface, the basic assumptions of the infinite line heat source (ILS) model and its improvement, the infinite line heat source model with an adiabatic boundary condition (ILS-ABC), might not be satisfied ...

Liquid atomization relies on a variety of forces that disturb the surface of the liquid. In the case of flow-blurring (FB) atomization, turbulent structures are induced within the liquid channel to achieve this effect. It is known that the transition from the conventional flow-focusing ... En savoir plus
A fundamental understanding of the transport phenomena in microfluidic channels is critical for systematic design and precise control of such miniaturized devices towards the integration and automation of Lab-on- a-chip devices. Electroosmotic flow is widely used to transport and mix ... En savoir plus
Annular Linear Induction Pump (ALIP) is used for pumping liquid metal in fast reactors and in experimental test facilities. In order to understand the transient behaviour of this pump, a 2-dimensional axisymmetric model in time domain is developed. The transient performance prediction ... En savoir plus
When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... En savoir plus
In metallurgy, the use of numerical models is popular because of the many coupled physical phenomena that occur during the various processes. For instance, the resulting shape and metallurgical state of a material are very sensitive to changes in temperature. The drop in temperature of ... En savoir plus
The separation of RBCs is needed in many biomedical devices. RBCs contain hemoglobin, which in turn consists of iron that helps transport oxygen throughout the body. The permeability of deoxygenated red blood cells is about (1 – 3.9e-6). The permeability of oxygenated red blood cells is ... En savoir plus
Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... En savoir plus
Incompressible flow field past a circular cylinder within parallel plate channel is very important in industry and science. As well known, beyond the Reynolds number based on the diameter of the cylinder and uniform flow velocity of 40, flow past a circular cylinder cannot hold its two ... En savoir plus
This research presents the design, simulation, and characterization of novel resonator structures based on the principles of coupling electric fields using periodic metamaterial-inspired configurations using COMSOL Multiphysics RF module. The resonators are meticulously crafted to ... En savoir plus
