Instantaneous velocity field measurement in densely-laden two-phase flows using Ultrasound Imaging Velocimetry

Ultrasound Imaging Velocimetry (UIV, also known as 'echo-PIV') has, since its introduction a decade ago, been regarded as a promising tool to characterize non-transparent flows. Prime application examples are particle-laden flows and (in vivo) blood flow. Virtually all studies so far have been validation/comparison studies in laminar flow. In...

Large Eddy Simulation of two-phase reacting flows

Large Eddy Simulation (LES) is now recognized as an efficient numerical tool to predict gaseous combustion in industrial burners, and a number of examples of applications can be found in the literature. In these examples, the accuracy and the predictive capacity of LES are clearly demonstrated, even for unsteady phenomena. However most...

A parallel finite element method for two-phase flows

A parallel finite element model for incompressible laminar two-phase flows is presented. A two-fluid model, describing the laminar non-equilibrium flow of two incompressible phases, is discretized by means of a properly designed Streamline Upwind Petrov-Galerkin (SUPG) finite element procedure. Such a procedure is consistent with a continuous...
