This paper presents numerical simulation results of the primary atomization of a turbulent liquid jet injected into a gaseous crossflow. Simulations are performed using the balanced force refined level set grid method. The phase interface during the initial breakup phase is tracked by a level set method on a separate refined grid. A balanced force finite volume algorithm together with an interf...

this paper is the representation of the computational and experimental methods of a new injector nozzle for a sequential port injection cng engine. the objective of this study was to review the previous research in the development of gaseous fuel injector for port injection cng engine converted from diesel engine. next, a simulation of the fuel flow of the new injector nozzle was made using flu...

Oxides of Nitrogen are the major emission from a diesel engine. It is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of NO is promoted. Various techniques are therefore employed to reduce the NOX emission like EGR, SCR, etc. In this present work a rotating injector is a tec...

The brightness and quality of electron beams in linacbased light sources are ultimately limited by the properties of the beam in the injector. It is thus important to have knowledge of the phase space distribution in addition to the rms emittance to provide an insight into high beam brightness formation mechanisms. A tomography technique has been used to reconstruct the transverse phase space o...

The high spatial resolution needed in self-consistent particle simulations can be achieved using adaptive mesh refinement techniques (AMR). In this paper the code SMOVE which is based on such an adaptive mesh is presented. It allows for accurate simulations with a high spatial resolution in the vicinity of the particle bunches. Furthermore, it offers the possibility of simulating long accelerat...

The particle-pushing PARMELA was used to design the photo-injector beamline of the Linac Coherent Light Source (LCLS) to be built at SLAC in 2005. PARMELA predicts that projected emittances smaller than 1.2 mm.mrad and slice emittance smaller than 1.0 mm.mrad will be achievable for 1nC, 10ps electron bunches with an S-band RF gun and an emittance compensating system. To benchmark PARMELA, compa...
