Wavepacket modulation in shock-containing jets
Petrônio A. S. Nogueira, Hamish W. A. Self, Aaron Towne +1
We propose a new approach to predict the modulation of wavepackets in shock-containing jets. With a modelled ideally expanded mean flow as input, an approximation of the shock-cell…

Wavepacket Modelling of Broadband Shock-Associated Noise in Supersonic Jets
Marcus H. Wong, Peter Jordan, Igor A. Maia +4
We present a two-point model to investigate the underlying source mechanisms for broadband shock-associated noise (BBSAN) in shock-containing supersonic jets. In the model presente…

Dynamic Evolution of a Transient Supersonic Trailing Jet Induced by a Strong Incident Shock Wave
Mohammad Rezay Haghdoost, Daniel Edgington-Mitchell, Maikel Nadolski +2
The dynamic evolution of a highly underexpanded transient supersonic jet at the exit of a pulse detonation engine is investigated via high-resolution time-resolved schlieren and nu…
