An Experimental Study on Micro Shock Tube Flow

An Experimental Study on Alcohol Flow in Micro-Channels

Experiments were performed to study the flow characteristics of ethanol and methanol flow in rectangular micro-channels using test models 1 and 2 (TM1, TM2). The TM1 and TM2 used were of 47 and 50 micro-channels in rectangular crosssection of equivalent diameters of 387 and 327 m respectively. The channel length of 192 mm were fabricated on a 304 stainless steel substrate (230 mm x 160 mm x 1....

An Experimental Study on Micro Clinching of Metal Foils with Cutting by Laser Shock Forming

This paper describes a novel technique for joining similar and dissimilar metal foils, namely micro clinching with cutting by laser shock forming. A series of experiments were conducted to study the deformation behavior of single layer material, during which many important process parameters were determined. The process window of the 1060 pure aluminum foils and annealed copper foils produced b...

Computational Study on Micro Shock Tube Flows with Gradual Diaphragm Rupture Process

Gas flows through micro shock tubes are widely used in many engineering applications such as micro engines, particle delivery devices etc. Recently, few studies have been carried out to explore the shock wave excursions through micro shock tubes at very low Reynolds number and at rarefied gas condition. But these studies assumed centered shock and expansion waves, which are generally produced b...

Experimental Study on the Effect of Magnetic Field on Critical Heat Flux of Ferrofluid Flow Boiling in a Vertical Tube

In the present work, the critical heat flux measurements were performed for the subcooled flow boiling of pure water and magnetic nanofluids (i.e., water + 0.01 and 0.1 vol.% Fe‌‌3O4) in a vertical tube. The effect of applying an external magnetic field on the CHF variation was studied experimentally as well. The obtained results indicated that the subcooled flow boiling CHF in the vertical tub...
