This paper will describe the dependence of capacitive accelerometer characteristics on the accelerometers physical dimension and its material properties. The sense element of the accelerometer is designed on the basis of a commercially available torsion based accelerometer technology. The sense element consists of an asymmetrically shaped flat plate of metal supported above a substrate surface by ...

This paper describes the characteristics of MEMS microchannel and various issues of its designing. Here the major parameters are pressure drop and heat transfer rate. Various structures are modeled and optimized to get a minimum pressure drop and maximum heat transfer rate. The simulation results provide the characterization for Temperature, Mass flow rate, Pressure drop and Reynolds number. Here ...

Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down the nuclear power under trip conditions. The Horizontally placed LISS pipes are placed perpendicular to the ...

The optimized design of a waveguide applicator has been proposed for superficial microwave hyperthermia using COMSOL Multiphysics 3.5a. In microwave hyperthermia cancer treatment body tissue is exposed to high temperatures using external and internal heating devices. Non-Invasive or external hyperthermia is used to treat tumors that are in or just below the skin (superficial). Non-invasive ...

Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials. Hence these materials are exposed to the transient heat loads up to 10MW/m^2. Thermo mechanical behavior of Graphite test mock-up under the transient heat ...

PEM fuel cells are very promising for portable applications. A key component of fuel cell is the flow field plate through which hydrogen will reach the anode, oxygen will reach the cathode and electron collection. Flow field plate made of silicon is not a good electrical conductor , so electrical contacts has to be attached to the Gas Diffusion Layer (GDL) for taking the power to outside ...

Electroosmotic flow of power-law fluids in a slit channel(1D) is analyzed. The governing equations are the Poisson–Boltzmann equation, the Cauchy momentum equation, Generalized Smoluchowski equation and the continuity equation are used to get shear stress, dynamic viscosity, and velocity distribution. Simulations are performed to examine the effects of ?H, flow behavior index, double layer ...
