Receptivity of the turbulent precessing vortex core: synchronization experiments and global adjoint linear stability analysis
J. S. Müller, F. Lückoff, P. Paredes +2
The Precessing Vortex Core (PVC) is a coherent structure that can arise in swirling jets from a global instability. In this work, the PVC is investigated under highly turbulent con…
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…
Investigation of the Exhaust Flow of a Pulse Detonation Combustor at different Operating Conditions based on High-Speed Schlieren and PIV
Mohammad Rezay Haghdoost, Daniel Edgington-Mitchel, Christian Oliver Paschereit +1
The exhaust flow of a Pulse Detonation Combustor (PDC) is investigated for different operating conditions. The PDC consists of two units, the deflagration to detonation transition…
On the nature of spectral proper orthogonal decomposition and related modal decompositions
Moritz Sieber, C. Oliver Paschereit, Kilian Oberleithner
The spectral proper orthogonal decomposition (SPOD) is a newly introduced extension of snapshot POD that recently gained attention but also brought up controversial issues. Within…
Transient evolution of the global mode in turbulent swirling jets: experiments and modal stability analysis
Lothar Rukes, Moritz Sieber, Oliver Paschereit +1
Modal linear stability analysis has proven very successful in the analysis of coherent structures of turbulent flows. Formally, it describes the evolution of a disturbance in the l…
