Euler characteristic techniques

In this section, a hexagonal SAW device based on LiNb03 substrate is modeled using hnite element technique. The wave propagation characteristics along the three different delay paths corresponding to crystal orientation with Euler angles (0, 90, 90),... 

Because of a vivid interest in spray combustion, quite a few papers deal with the effect of finely dispersed particles or droplets on the turbulence characteristics of jets and sprays. The interaction of particle dynamics and turbulence in these flows has prompted very fundamental stochastic approaches involving filtering and averaging techniques, probability density functions, and quadrature-based moment methods (Fevrier et al, 2005 Fox, 2012 Labourasse et al, 2007) which are beyond the scope of this chapter. Riber et al (2009) and Senoner et al (2009) obtained LES results for recirculating and evaporating two-phase flows, respectively, by both Euler-Lagrange and Euler—Euler methods and compared them mutually and with experimental data.
