Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... En savoir plus
We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... En savoir plus
Liquid metals are the extensively used as coolants in nuclear reactors.However, the heat transfer mechanism differs significantly in low Prandtl number heavy liquid metals (HLM’s) than those observed in common fluids. It is crucial to have the accurate heat transfer correlation for the ... En savoir plus
Interstitial fluid pressure (IFP) is elevated in tumors. Owing to this elevated IFP, the interstitial fluid velocity (IFV) is negligible throughout the tumor but significant near the tumor margin. Any therapeutic strategy that can lower IFP will improve drug convection within the tumor ... En savoir plus
Liquid metals are foreseen as a multipurpose coolant in fusion blanket systems. However, the strongly magnetic environment of the fusion reactor hinders the regular flow of the liquid metal. It interacts with transverse magnetic field and produces a Lorentz force opposing the flow, ... En savoir plus
Metamaterial [1, 2] is an artificially structured material where it’s electrical (ϵ), magnetic (μ) and its refraction properties (n) are simultaneously negative in narrow frequency band. Currently, metamaterials are being widely used in microwave and radio frequencies as devices [3, 4] ... En savoir plus
Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... En savoir plus
Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured ... En savoir plus
An easily implemented method is devised, where analytical criteria for the occurrence of streamer discharges in strong electric fields are evaluated. This is highly useful when designing high voltage power transmission systems and components where the insulation is provided by a gas, e ... En savoir plus
Micro Wire EDM (Electro Discharge Machine) process is a highly reliable and non-conventional process to manufacture precise and accurate complex shapes in various types of conducting materials. The accuracy of this process is measured in micrometres, thus making it superior to other ... En savoir plus
