Conditional Moment Closure Modeling of Turbulent Spray Combustion in a Direct Injection Diesel Engine

which are in a nonconservative form. Global conservation is not guaranteed if integration is performed for Eqs. (2) and (3), which do not include PDF inside the temporal and spatial derivatives. On the other hand nonconservative forms allow a relatively coarse mesh since conditional averages show much less spatial dependence than PDF weighted Favre averages. Here η ρ ρ η ≡ and the scalar dissip...

Modeling Spray Pyrolysis Deposition

The deposition of a thin tin oxide film allows for the manufacture of modern gas sensors. Spray pyrolysis deposition is used to grow the required thin films, as it can be seamlessly integrated into a standard CMOS processing sequence. A model for spray pyrolysis deposition is developed and implemented within the Level Set framework. Two models for the topography modification due to spray pyroly...

Inconsistencies in moment methods.

In this work we show that moment methods devised to solve the Boltzmann kinetic equation for a simple gas exhibit some inconsistencies. This puzzle, which also appears for the Chapman-Enskog method, is solved resorting to a perturbative expansion in the Knudsen number, thus allowing for a clear way to arrive at a closure condition.

Spray deposition on plant surfaces: a modeling approach

Pesticides are widely used in agriculture for the management of pests (weeds, insects or pathogens). They are generally applied as a spray to cover the target (e.g. an insect, leaf surfaces or part of a plant) with pesticide-laden droplets. Spray may, however, be lost to nontarget areas within a crop through deposition on to the soil or on non-target plant surfaces. The plant architecture of th...
