A particle-fluid numerical model for liquid sprays

摘要: Abstract A numerical technique has been developed for computing the behavior of atomized non-evaporating liquid sprays injected into a gaseous environment. The same technique, however, is applicable to general incompressible flows containing particles or droplets. method consists fully-interacting combination Eulerian fluid and Lagrangian particle calculations. interaction calculations are performed simultaneously noniteratively. description avoids diffusion, allows individual attributes, such as size, composition, etc., be statistically assigned each particle. Numerical comparisons with experimental data given some typical diesel engine fuel injection.
