Numerical and experimental study of confluent jets supply device with variable airflow

Autor: Andersson, Harald

In recent years, application of confluent jets for design of ventilation supply devices has been studied. Similarly, numerus studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of

Numerische und experimentelle Untersuchung der fluiddynamischen Eigenschaften von Strahlströmungen in begrenzten Räumen

Autor: Ringleb, Ansgar

In der vorliegenden Arbeit wurden Strömungen räumlich begrenzter Strahlen untersucht. Zum einen wurde die Ausströmung eines runden Strahls in ein Rohr betrachtet, der sog. begrenzte Strahl. Zum anderen wurde die Ausströmung von 7 hexagonal angeor
