The compressible starting jet

Peña Fernández, Juan José (2018)

Jets are involved in numerous industrial applications and in nature: fuel injection, jet engines, volcanic jets, air-bag devices, but also water jet cutters, jet packs (rocket belts), jet injectors for vaccination, astrophysical jets, etc. Continuous jets have been already studied in the incompressible and compressible case for almost a century, focused mainly on the characterization of the flu...

Simulation und Analyse einer Verdichterkaskade mit aktiver Strömungsbeeinflussung

Gmelin, Christoph (2018)

Axiale Verdichter erreichen heutzutage sehr hohe Gesamtdruckverhältnisse, wozu eine hohe Anzahl von Verdichterstufen notwendig ist. Bei Flugtriebwerken stellt das Einsparen ganzer Stufen eine Möglichkeit dar, gleichzeitig das Gewicht und den Bauraum zu reduzieren. Für stationäre Gasturbinen wird der Teillastbetrieb mit steigendem Anteil an regenerativen Energien immer bedeutsamer. Beide Forderu...

Numerical simulation of a regional train in cross-wind

Eichinger, Sándor ; Sima, Mikael ; Thiele, Frank (2015)

In this work numerical investigations of regional trains were carried out studying the prediction accuracy of the aerodynamic load in cross-wind assessment of rail vehicles. The main focus is on 30° yaw angle. Two domain setups, one representing the wind tunnel setup and another more generic one, were investigated and validated against available measurements comparing load coefficients. Importa...
