Mechanical variations on the surfaces of copper samples are performed to analyse the effect of electrical & thermal CC on temperature. The contact conductance (CC) model is a collaboration of electrical, thermal and deformation model and hence, three physics namely, SM, EC and HT, ... En savoir plus

An Internal Combustion Engine (IC Engine) is a heat engine where combustion of air-fuel mixture occurs in a combustion chamber. The combustion of chemical fuels produces energies in form of heat and pressure. The pressure energy then converted to mechanical work through piston, ... En savoir plus

Waste heat is inevitable in any heat engine while producing useful mechanical work. A lots of heat energy is often dissipated to surrounding environment as waste, which limits the system efficiency. In almost all of the industrial processes, half of the heat energy is turned into waste ... En savoir plus

The disk resonator gyroscope (DRG) is a meso-scale, high performance, compact and planar new generation Coriolis vibratory gyroscope which is suitable for space applications. Angular rate measurement utilizes the precession of a pair of degenerate modes of a perfectly balanced ... En savoir plus

Micro-Electro-Mechanical system (MEMS) can be understood as miniaturized mechanical and electromechanical elements that include sensors, actuators, and microelectronics. Capacitive accelerometers are the devices which measure the acceleration on a surface using capacitive sensing ... En savoir plus

The spindle is regarded as the heart of the CNC machine tool. Typically, the spindle is operated using the belt or gear drives to realize the relative motion between workpiece and cutting tool. However, they cannot be operated at high speeds due to power transmission losses, thus ... En savoir plus

A solar thermal power plant comprises of an optical system, heat source and power block. Optical system collects direct sunlight and concentrates it onto the receiver (shown in figure 1). The receiver intercepts the concentrated sunlight and converts it to heat. Finally, the heat is ... En savoir plus

Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... En savoir plus
