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 ...

This abstract addresses the effect of scaling in air gap MOSFETs and determination of functional relationship between scaling parameter and sensitivity, frequency response. The modelling of the MOSFET and its simulations has been carried out using COMSOL Multiphysics. An air Gap MOSFET in its simplest form can be imagined to be one obtained by replacing the dielectric in a MOSFET with air. The ...

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 ...

Proton exchange membrane fuel cells (PEMFCs) were investigated using COMSOL Multiphysics with the AC/DC Module and Chemical Engineering Module. Simulation may be used to increase the performance while decreasing the cost of the catalyst later (CL). Experimental validation of single and multi-layer CL was performed for varied PBI electrolyte content. The validated model was used to investigate the ...

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 ...

Evanescent-wave optical waveguide is widely used as sensing platform for chemical/biological sensor applications. Our research group contributed to on-chip IR sensor technology and made recent progress in miniaturizing such devices utilizing quantum cascade lasers (QCL) in combination with planar GaAs/Al0.2Ga0.8As waveguides. Furthermore progress is reported toward microfabricated Mid-infrared ...

All particles in suspension have a zeta potential, or surface potential. Its measurement is extremely important for predicting the formulation stability across a wide range of industries including food, ink and pharmaceuticals, water purification and medical devices. Zeta potential is not measurable directly but it can be calculated from an experimentally determined electrophoretic mobility. ...

The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape bulk products having good surface finish with better mechanical properties. Pressing punches of suitable profile ...

Deep Brain Stimulation (DBS) has been established as an effective treatment for Parkinson's disease and other movement disorders. The stimulation is currently administered using tetrode-macroelectrodes that target the Subthalamic Nucleus (STN). This often leads to side effects which bias the surrounding areas, e.g. the speech centre. Targeting a specific brain region can better be achieved with ...
