The flow around a seal-vibrissa-shaped cylinder (SVSC) is numerically investigated using
the large eddy simulation framework at a Reynolds number of 20 000. Compared with a …

Sudden changes of flame shape are an undesired, yet poorly understood feature of swirl
combustors used in gas turbines. The present work studies flame shape transition …

Due to the existence of the upstream and downstream gap, the flow dynamics around a
separated triple-box girder becomes quite complex. This work explores the flow dynamics …

This study investigated the performance of proper orthogonal decomposition (POD), discrete
Fourier transformation (DFT), time-domain spectral proper orthogonal decomposition (td …

Precessing vortex core (PVC), a typical vortex structure, universally exists in swirling flow
fields and originates from the Kelvin–Helmholtz instability of the swirling shear layer. In the …

This overview collects a range of well characterized experiments used in the step-wise
validation of turbulent combustion models, from gas phase non-premixed jet flames to spray …

Through comparing with the tandem circular and elliptic cylinders with the same
characteristic dimensions, the behavior of flow and flow-induced noise generated around …

This paper presents an experimental study of a strongly swirling turbulent flow with the
formation of a precessing vortex core (PVC) that emerges at the outlet of a tangential swirler …

A method is developed to estimate the properties of a global hydrodynamic instability in
turbulent flows from measurement data of the limit-cycle oscillations. For this purpose, the …

The generation and turbulent transport of temporal equivalence ratio fluctuations in a swirl
combustor are experimentally investigated and compared to a one-dimensional transport …
