We have investigated dynamic behavior of a dust flow with velocity shear in RF plasmas. In this study, neutral drag force by the neutral gas ejected from small nozzles is used for driving directional dust flows with velocity shear. The strength of the velocity shear can be controlled over a wide range by adjusting the direction of the nozzles and the flow rate of the neutral gas. The dust parti...
This paper reports a method to control the bubble size generated in a microfluidic flow-focusing configuration. With an ultrasonic transducer, we induce acoustic streaming using a forward moving, oscillating gas-liquid interface. The induced streaming substantially affects the formation process of gas bubbles. The oscillating interface acts as a pump that increases the gas flow rate significant...
Various analytical, semi-analytical, and empirical models have been proposed to characterize rate and pressure behavior as a function of time in tight gas and shale gas systems featuring horizontal wells with multiple hydraulic fractures. Despite a few analytical models, as well as a small number of published numerical studies, there is currently little consensus regarding the large-scale flow ...
The effect of natural convection on the uncertainty calculation of the MIKES dynamic gravimetric gas mass flow measurement system (DWS) is studied in this paper. The magnitude of the uncertainty component due to varying shear stress rate at the wall of the cylinder is studied theoretically at two different varying temperature models. Based on the obtained results, the contribution of the compon...
Unconventional gas resources from tight-sand and shale gas reservoirs have received great attention in the past decade around the world because of their large reserves and technical advances in developing these resources. As a result of improved horizontaldrilling and hydraulic-fracturing technologies, progress is being made toward commercial gas production from such reservoirs, as demonstrated...
In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...
Batch experiments to remove ammonia from food waste digestate were set up, and preliminary runs undertaken. These experiments were based on gas stripping in a heated column reactor; the effects of different temperatures (35, 55 and 70 degrees C) and gas flow rates (0.125, 0.250 and 0.375 L(biogas)L(digestate)(-1)min(-1)) were considered using biogas as the stripping gas. At 35 degrees C, an inc...
Our aim is to develop and optimize a model for a dielectric barrier discharge used as a chemical reactor for gas treatment. In order to determine the optimum operating conditions, we have studied the influence of the gas flow rate, reactor geometry and applied voltage parameters on the discharge characteristics. For this purpose, a two-dimensional time-dependent fluid model has been applied to ...
