An experimental investigation of the flow field near liquid fuel jets injected transverse to a hot supersonic air stream
The flow field associated with injecting liquid fuel jets into a hot, supersonic air stream was investigated for three different liquids; kerosene, carbon disulfide and water as a non-burning control. The tests were conducted at a Mach number of 1.8 with a nominal stagnation pressure of 100 psia …

An Experimental Investigation of the Injection Process in a Direct-Injected Natural Gas Engine Using PLIF and CARS
… the conservation equations effectively collapsed fuel jet penetration measurements under both motoring and stationary piston conditions. The scaling factors are based on the pseudo diameter of the jet, which is the diameter of an equivalent sonic jet expanded to match the in-cylinder conditions. …

The effect of flow structure on the combustion and heat transfer in a scramjet combustor
… effective in promoting lateral spreading of the fuel jets. The incomplete penetration of the fuel jets in the direction normal to the walls was a major limiting factor in the amount of mixing that could occur for both configurations. In addition, the proximity of the burning shear layer to the …

A Five-Zone Model for Direct Injection Diesel Combustion
… internal structure of direct injection diesel fuel jets as well as empirical correlations predicting jet development and structure. This information was used to create a diesel cycle simulation model using C language including compression, fuel injection and combustion, and expansion processes. …

Spray visualization and characterization of a multi variable circular orifice (MVCO) injector coupled with a swirl adapter for diesel reformer applications
The fuel spray generated by the injector is of primary importance to mixing and hence, combustion efficiency, due to the extremely short time scale of the combustion event inside an internal combustion engine. In this respect, the aim of the fuel injection system is to atomize the fuel droplets as …

Computational fluid dynamics modeling of a large bore two-stroke natural gas engine
Natural gas fueled engines have been used for many years in stationary applications such as gas compression and electric power generation. In the United States alone, there are over 8,000 large bore (bore >30 cm) slow speed (speed < 500 rpm) natural gas engines in use. The most common configuration …

An Integrated Aerodynamic-Ramp-Injector/ Plasma-Torch-Igniter for Supersonic Combustion Applications with Hydrocarbon Fuels
The first integrated, flush-wall, aero-ramp-fuel-injector/plasma-torch igniter and flame propagation system for supersonic combustion applications with hydrocarbon fuels was developed and tested. The main goal of this project was to develop a device which could be used to demonstrate that the …
