By Lefebvre, Arthur Henry; McDonell, Vincent G

The moment variation of this long-time bestseller offers a framework for designing and figuring out sprays for a wide range of engineering purposes. The textual content comprises correlations and layout instruments that may be simply understood and utilized in bearing on the layout of atomizers to the ensuing spray habit. Written to be obtainable to readers with a modest technical historical past, the emphasis is on software instead of in-depth idea. a number of examples are supplied to function beginning issues for utilizing the data within the booklet. total, this can be a completely up-to-date variation that also keeps the sensible concentration and clarity of the unique paintings by way of Arthur Lefebvre.

Efficient Implementation of High-Order Accurate Numerical Methods on Unstructured Grids

This thesis makes a speciality of the improvement of high-order finite quantity tools and discontinuous Galerkin tools, and offers attainable strategies to a few vital and customary difficulties encountered in high-order tools, akin to the shock-capturing procedure and curved boundary therapy, then applies those tips on how to resolve compressible flows.

Sample text

The deformation is governed by a dimensionless group, μCSD/σ, where μC is the viscosity of the continuous phase and S is the maximum velocity gradient in the external flow field. Breakup of the drop occurs at a critical value of the Weber number that depends on the continuous flow field. The experimental data obtained by Meister and Scheele [43] demonstrate the effects of the viscosities of both the dispersed and continuous phases, as well as their viscosity ratio, on atomization. At this point it is appropriate to make a distinction between the dispersed and continuous phases.

Atomization. The jet disrupts completely at the nozzle exit. Average drop diameters are much less than the jet diameter. 1. Rayleigh jet breakup. This is caused by the growth of axisymmetric oscillations of the jet surface, induced by surface tension. Drop diameters exceed the jet diameter. First wind-induced breakup. The surface tension effect is now augmented by the relative Se In a key study, Reitz [64] attempted to resolve some of the uncertainties surrounding the Ohnesorge chart. His analysis was based on interpretation of the data on diesel sprays obtained by him and other workers, including Giffen and Muraszew [3] and Haenlein [12].

21) σ where u 2 is the average value of the squares of velocity differences over a distance equal to Dmax across the whole flow field [7]. For isotropic turbulence, the main contributions to the kinetic energy are made by fluctuations where the Kolmogorov energy distribution law is valid. 22) where, according to Batchelor [34], C1 = 2. 23) σ and dimensional analysis on the assumption that only σ, ρ A, and E determine the size of the largest drops. 22. Clay’s apparatus consisted of two coaxial cylinders, of which the inner one was rotated.
