Pressure swirl nozzles are widely applied in spray cooling, dust removal, and fuel injection.
To better connect the nozzle structure with the internal flow to analyze their influence on …

Spray characterization in a novel twin-jet airblast injector is reported in this paper with the
focus on the study of the effect of injector air swirl on droplet characteristics and dispersion …

The twin-fluid atomizer employing the cross-stream mixing arrangement for air and liquid
prior to the orifice exit is investigated with a scaled-up size transparent injector. Simplistic …

Spray drop size distribution generated by atomization of fuel influences several facets of a
combustion process such as, fuel-air mixing, reaction kinetics and thrust generation. In a …

A precessing vortex core (PVC) is a self-excited helical instability that results from the
precession of the vortex core around the flow axis in the upstream region of a vortex …

In this paper, we present detailed experimental measurements and analysis on the spray-
flow interaction emerging from a newly designed high shear injector. The injector consists of …

The spray characteristics of different regions downstream of swirl cups play a critical role in
cold start and re-ignition of gas turbines. The spray measurements were performed at the …

Coupling of spray with the coherent structures of highly turbulent flow has been a long-
standing problem, especially in the context of liquid fuel delivery systems in gas turbine …

The swirl cup airblast fuel injector is widely used in modern low-emission gas turbine
combustors. It is important to understand the underlying physics in the interaction between …
