There are many incentives to increase the fuel efficiency of combustion processes. This paper looks at two available options to achieve this goal. The former aims to develop an experimental method that can analyze combustion at extremely high pressures to improve the understanding of high pressure H2/air combustion. Experimental data has been lacking a suitable combustion diagnostic to visualiz...

• This paper describes a computational study of the thermal and chemical nonequilibrium occuring in a rapidly expanding flow of high-temperature air transported as a free jet from an orifice into lowdensity stationary air. Translational, rotational, vibrational and electron temperatures are treated separately, and in particular the vibrational temperatures are individually treated; a multi-vibr...

Aeration devices are introduced along chute spillways and at bottom outlets to prevent cavitation damage in high velocity flows. Bottom aerators are characterised by large quantities of air entrained along the jet interfaces but also by a strong de-aeration process near the impact of the water jet with the spillway bottom. In this paper, the aeration and de-aeration occurring respectively in th...

Electrospinning uses electrical forces to produce polymer fibres with nanometre-scale diameters. Electrospinning occurs when the electrical forces at the surface of a polymer solution or melt overcome the surface tension and cause an electrically charged jet to be ejected. When the jet dries or solidifies, an electrically charged fibre remains. This charged fibre can be directed or accelerated ...

T availability of relatively cheap small jet aircrafts suggests a new air transportation business: dial-a-flight, an on-demand service in which travelers call a few days in advance to schedule transportation. A successful on-demand air transportation service requires an effective scheduling system to construct minimum-cost pilot and jet itineraries for a set of accepted transportation requests....

through these catheters," we recommended in our case report that jet ventilation through these catheters shodd not be necessary during the brief period of tube exchange.' According to the editorial of Benumof,' air entry should not exceed air exit. The incidence of complicating barotrauma may be decreased by selecting a properly sized exchange catheter in proportion to the size of the endotrach...

Several methods have been employed to comb/stretch single DNA molecules such as magnetic [1] and laser tweezers [2], movement of an air-water interface [3] and air jet guided fluid flow [4]. However, the scientific community still lacks a feasible technique to directly deposit and comb large DNA molecules on surfaces. A novel method to comb large DNA molecules at the micron and ultramicro scale...
