Einfluss von Filterstruktur und Gießsystem auf die Filtrationseffizienz im Aluminiumformguss
… wird sich durch CFD-Simulationen mittels Flow 3D und durch Gießversuche im Technikum und der Industrie genähert. Die Simulationen ergaben eine Steigerung der Filtrationseffizienz um 20% - 30% bei der Erhöhung der Makroporosität des Filters von 20 ppi auf 30 ppi in Abhängigkeit von der …

Numerical Study of Turbulent Characteristics and Aeration Patterns in Breaking Surge Waves
… surge waves are caused by a sudden change in flow. 3D numerical simulation provides a holistic approach to simulate the turbulent behaviour behind a breaking surge wave. A combination of Volume of Fluid (VOF) method and Large Eddy Simulation (LES) is utilized for Froude numbers ranging from …

Nerva-derived reactor coolant channel model for Mars mission applications
… Reactor (NDR) coolant channel; The CFD code FLOW-3D was used to model the flow of gaseous hydrogen through the core of a NDR. Hydrogen passes through the core by way of coolant channels, acting as the coolant for the reactor as well as the propellant for the rocket. Hydrogen enters the …

Numerical modeling of gravity die casting processes with solidification present during filling
… casting mold filling and solidification with FLOW-3D CAST®’s gravity die casting workspace. Simulations and instrumented castings in the literature have shown casting into a thin plate, monolithic mold cavity using top-gated gravity die casting produces an undesirable temperature gradient in …

A virtual flow meter to develop velocity-index ratings and evaluate the effect of flow disturbances on these ratings
Stream flow records are typically estimated with the use of empirical rating curves. The conventional rating method relates stage to discharge, however at sites prone to flow reversals, changes in stream bed roughness, backwater, and tidal effects, a stage-discharge rating is not unique and a …

Vibration assisted filling of thin section castings
… thin wall casting i] discontinuous propagation flow in vibration conditions; and ii] continuous propagation flow without vibration. These mechanisms may be acting to modify the contact angles between liquid metal and a wall of the mould. Experiments also showed that two features of the …

Full 3D Blood Velocity Mapping and Flow Quantification from Doppler Echocardiographic Images
… by describing two novel methods to calculate<br/>3D blood velocity and flow within the heart using 3D colour Doppler images. The<br/>principal goal of both methods was to overcome the main limitation of Doppler<br/>systems which is that the Doppler effect only measures one component of the …
