Structure 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 کاملComputations of Turbulent Evaporating Sprays
A computational study of turbulent evaporating sprays is reported. The major focus is to study the structure of turbulent evaporating sprays and to examine the sensitivity of their vaporization behavior to transient liquid-phase processes. Three models considered to represent these processes are the thin-skin, infinite-diffusion, and diffusionlimit models. Favre-averaged equations with a k-s-g ...
متن کاملSimulation of Oblique Evaporating Diesel Sprays, and Comparison with Empirical Correlations and Simulated Straight Sprays
The innovation in software analysis and various available programming facilities have urged the designers at various levels to do indispensable calculations for engine flows. Presently, the 3-D analysis approach is under practice to do simulations for various parameters involving engine operations using various softwares, “Fluent” being the trendiest at the moment for CFD modeling. The present ...
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...
متن کاملNumerical Analysis of Eulerian Multi-fluid Models in the Context of Kinetic Formulations for Dilute Evaporating Sprays
The purpose of this article is the analysis and the development of Eulerian multi-fluid models to describe the evolution of the mass density of evaporating liquid sprays. First, the classical multi-fluid model developed in [Laurent and Massot, Combust. Theor. Model. 5 (2001) 537–572] is analyzed in the framework of an unsteady configuration without dynamical nor heating effects, where the evapo...
