We address highly swirling, confined-bluff-body-flow evolving through a burner; particularly,
contributions of the swirling motion to a central-recirculation-zone (CRZ) downstream the …

Direct numerical simulation is used to study unconfined coaxial jets under the influence of
strong swirl imparted to the outer jet. Spectral proper orthogonal decomposition is employed …

At low altitudes during rocket flight, the atmospheric pressure is higher compared to the
design pressure of the nozzle at the exit. This leads to the formation of overexpansion shock …

Axisymmetric numerical simulations are used to assess the swirl-induced stabilization of low-
Mach-number non-premixed jet flames at a moderate Reynolds number (R e= 200). Using a …

Submersible thrusters (STs) are crucial for applications such as wastewater treatment, but
their energy decay mechanisms and flow characteristics remain inadequately understood …

Purpose The purpose of this study is to investigate the effect of coaxial swirlers on acoustic
emission and reduction of potential core length in jet engines. Design/methodology …

The effects of Reynolds number on flow and mixing characteristics of a merged single
swinging jet induced by a V-shaped fluidic oscillator were studied experimentally. The jet …

Due to the heavy consumption of the fossil fuels in the transportation sector and the furnace
factory, a large amount of soot is discharged and seriously threatened the environment and …

In combustion applications such as gas turbines, swirling jets are used to generate a vortex
breakdown recirculation region that serves as a non-invasive flame stabilizer. The present …

This paper investigates the flow features of a four-sector swirling jet horizontally discharged
into a linear density stratification environment at a Reynolds number of 3023. Three regions …
