A multi-Gaussian quadrature method of moments for simulating high Stokes number turbulent two-phase flows (original) (raw)

A multi-Gaussian quadrature method is proposed for simulating high Stokes number turbulent two-phase flows, addressing limitations of existing methodologies like Lagrangian Monte-Carlo and the Mesoscopic Eulerian Formalism (MEF). By employing quadrature techniques, which solve for the stresses modeled in MEF, the new approach effectively accounts for Particle Trajectory Crossings (PTC) in the correlated motion of sprays. This method utilizes a statistical framework that employs multiple Gaussian distributions to better capture complex flow behaviors, particularly in configurations involving significant turbulence and high Stokes numbers.
