It was done inoptimization palace and with a capacity of CHP as a production resource with the aim to increasethe reliability capacity. Decrease the loss and provide the electrical and thermal energies ofindustrial city. The f...

The application of a temperature difference (∆T) across a solid conductor causes mobile charge carriers to diffuse from hot to cold regions, giving rise to a thermoelectric voltage ∆V=-Se. ∆T. The prefactor Se is called the thermopower or Seebeck coefficient which describes how electrical energy can be generated from the thermal energy. The great majority of today’s thermoelectric (TE) research...

We present a comprehensive study on a high reliability RF-MEMS switch with an active thermal recovery capability to counteract stiction. Applying finite element (FE) simulations we investigate the complete recovery process including mechanical, electrical, thermal and fluidic effects. The experimentally calibrated thermo-mechanical FE-model is used to extract key parameters of the recovery proc...

Presently, the only commercially available power generating thermoelectric (TE) modules are based on bismuth telluride (Bi2Te3) alloys and are limited to a hot side temperature of 250 °C due to the melting point of the solder interconnects and/or generally poor power generation performance above this point. For the purposes of demonstrating a TE generator or TEG with higher temperature capabili...

Cogenra company has created a low concentration PV/Thermal system that produces both thermal energy and electricity simultaneously, mainly for commercial and industrial applications. The realization of a system that combines photovoltaic modules, solar thermal collectors and concentrating mirrors makes it a complicated system to study. So far, only simple studies have been made on Cogenra’s LCP...

An experimental platform was designed and built for testing the thermal performance of a water/steam cavity receiver. The experimental platform was utilized to investigate the start-up performance and operation characteristics of the receiver. The electrical heating mode was chosen to simulate the non-uniform distribution of heat flux on the surface of absorber tubes inside the cavity. During s...

with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

Light emitting diodes, LEDs, historically have been used for indicators and produced low amounts of heat. The introduction of high brightness LEDs with white light and monochromatic colors have led to a movement towards general illumination. The increased electrical currents used to drive the LEDs have focused more attention on the thermal paths in the developments of LED power packaging. The l...
