The paper describes an efficient way to couple 1D System AMESim and 3D CFD EOLE softwares together for the simulation of Diesel injection. The strong coupling model is based on a co-simulation approach. AMESim and EOLE are complementary tools with complementary approaches. From their combination, a very efficient tool is built able to model all the...
Conference Paper

In high pressure diesel injection processes, the flow is led by mass transfer mechanisms. Indeed, cavitation of the flow occurs due to the drop of the static pressure locally induced by geometrical constraints: in the needle seat and at the hole inlets. The presence of unsteady cavitation which depends on characteristics of the holes and of the nee...

Progress in Diesel spray modelling highly depends on a better knowledge of the instantaneous injection velocity and of the hydraulic section at the exit of each injection hole. Additionally a better identification of the mechanisms which cause fragmentation is needed. This necessitates to begin with a precise computation of the two-phase flow which...

... Although observing cavitation inside nozzle orifices is a difficult task, experimental data, especially at the nozzle outlet, are needed to enhance our general knowledge on high pressure injection processes and to provide reliable initial conditions for numerical simulations (Ménard et al., 2007;Gorokhovski and Herrmann, 2008;Marcer et al., 2008;Lebas et al., 2009). Obtaining quantitative information as velocity profiles is even more complicated. ...
... Several authors have taken this approach to different generations of injectors in order to better understand their dynamics. Most of them have assumed the fuel flow as isothermal [11][12][13][14]. The authors have also assumed this hypothesis in previous works [15][16][17][18]. ...
... The widely-applied sharp interface capturing method Volume of Fluid (VOF) technique [36,43,46,47] has been chosen to capture the liquid/gas interface. The model is similar to the homogeneous model, where a single momentum equation is calculated for all phases that interact using the VOF model. ...
