Direct Injection of Natural Gas/Liquid Diesel Fuel Sprays
Dual-fuelling provides a suitable method for operating compression-ignition engines on alternative fuels. The CFD package Fluent is being used to model the direct-injection of two such fuels simultaneously into an engine. The CFD models have been initially calibrated using high-speed photographic visualisation of the jets. Different orientations and staging of the jets with respect to each othe...
متن کاملStructure of Evaporating Diesel Sprays
Performance of compression ignition engine is known to be spray characteristics related. Precise experimental information on fuel sprays is of utmost importance to model the fuel spray formation and its development in the engine combustion chamber. The previous experimental work of the present author on non-evaporating sprays produced by using a FIAT single-hole orifice type nozzle and a distri...

متن کاملSoot and Temperature Measurement in Diesel Sprays
Production of soot in high pressure diesel sprays is known to be dependent on combustion chamber temperature and pressure. To a lesser extent, the injector type and injection pressure also influence soot formation. In real engines, separating the individual role of these parameters is difficult as they are closely coupled. Here we present an optically based method to measure both temperature an...
متن کاملEulerian quadrature-based moment models for dilute polydisperse evaporating sprays
Dilute liquid sprays can be modeled at the mesoscale using a kinetic equation, namely the Williams-Boltzmann equation, containing terms for spatial transport, evaporation and fluid drag. The most common method for simulating the Williams-Boltzmann equation uses Lagrangian particle tracking wherein a finite ensemble of numerical “parcels” provides a statistical estimate of the joint surface area...
