ENO filters are developed and compared with classical ENO schemes, TVD filters, and classical TVD schemes. The amplitude of the numerical dissipation provided by the filtering pass is computed by means of the artificial compression method (ACM) switch and ...
The deformation-induced macrosegregation in continuous casting of steel has been simulated using a finite-volume scheme. For that purpose, a two-dimensional heat-flow computation was first performed in a Eulerian reference frame attached to the mold, assum ...
A numerical modelling approach, used for the analysis of stable brine displacement results, is described. The purpose of the analysis is to evaluate recent theoretical advances in modelling of density-dependent flow and transport. The data analysis involve ...
We present a formulation for accommodating defective boundary conditions for the incompressible Navier--Stokes equations where only averaged values are prescribed on measurable portions of the boundary. In particular we consider the case where the flow rat ...

After the first two successful editions of the Symposium on Ultrasonic Doppler Methods for Fluid Mechanics and Fluid Engineering (ISUD), held at PSI, Villigen, Switzerland in 1996 and 1999, we are very pleased to organize this third edition for the first t ...
Among the different negative cavitation effects that are associated with the cavitation presence (efficiency drop, noise and vibrations etc.), cavitation erosion is still one of the main limiting features in the modern trend towards designing hydraulic mac ...
We consider the incompressible, isothermal and inertialess flow of an Oldroyd-B viscoelastic fluid in the absence of body forces. We report numerical results on the simulation of unsteady flow of an Oldroyd-B fluid by spectral element methods. Several tech ...
Numerical simulation of the unsteady turbulent flow in a three-dimensional draft tube geometry is performed. The investigation is carried out with a commercial finite volume solver implementing the Reynolds averaged Navier-Stokes equations. The modeling of ...

Mixing liquids at the micro-scale is difficult because the low Reynolds numbers in microchannels and in microreactors prohibit the use of conventional mixing techniques based on mechanical actuators and induce turbulence. Static mixers can be used to solve ...
An algorithm is proposed for the simulation of unsteady viscous stratified compressible flows. The advantage of the method is its capability to deal with a broad range of subsonic Mach numbers, including nearly incompressible flows, with a single modelling ...
