For increasing first law efficiency in terms of COP and Second law efficiency (Exergetic Efficiency) of VCR systems.the experiment is performed on VCR system to study the effect of silver oxide Nano particle(50nm) in base fluid of ethyl glycol (50:50 ratio with water) with concentration factor 0.02 to 0.06g by volume % on hot side of system (condenser side). For high efficiency out-put, the pla...

the continuous development of global economy with decreasing in available hydrocarbon sources and increasing discovery and extraction costs due to decrease in-situ oil and gas reservoir, displays the necessity of using new techniques for the improve rate of penetration and productivity in well. nanotechnology has already contributed significantly to technological advances in the energy industri...

nano fillers are part of new studies to enhance various properties of fluids and solids. for example, adding nanoparticles as an enforcement in nanocomposites or as an additive to improve thermal or electrical properties in nano-fluids are of extreme importance in science and industry. there are numerous methods to uniformly disperse nanoparticles in fluid and solid phase. one of the well-used ...

In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...

It is generally acknowledged that a hanging cantilevered pipe conveying fluid becomes unstable by flutter-type instability at critical flow velocity; moreover, the undergoes periodic self-excited oscillations in post-flutter region. Additionally, velocity increases when magnetized exposed to an actuating parallel magnetic field. The question arises as whether field leads lessening oscillation a...

The temperature variation rule of nano-magnetic fluid in the specific magnetic field and the effect on the treatment of malignant glioma were examined. The temperature variation of nano-magnetic fluid in the specific magnetic field was investigated by heating in vitro, and cell morphology was observed through optical microscopy and electron microscopy. MTT detection also was used to detect the ...
