A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for ...

Turbulent flows past lateral cavities play an important role in the transport of contaminants in rivers and streams. Cavities are surface storage zones, where large-scale unsteady coherent structures are the leading ...

Here we present two-phase flow nonlinear parameter estimation for HFC's flow through capillary tube-suction line heat exchangers, commonly used as expansion devices in small refrigeration systems. The simplifying assumptions ...

This work presents a numerical investigation of three dimensional viscoelastic free surface flows. In particular, using two different numerical methodologies, we have simulated a typical free-surface benchmark flow problem: ...

Turbulent ows past lateral cavities in rivers and open channels play an impor- tant role in many environmental and geophysical applications. Large-scale coherent structures produced in the cavity are the most important ...
