LES of Jets and Sprays Injected into Crossflow
… gas turbine combustors. The jet in crossflow (JICF) is used both for cooling and for injecting liquid fuel into the air stream prior to combustion. The numerical simulations regard three space dimensions and track also the flow dynamics by integrating the governing equations in time. The …

Large eddy simulations of hydrogen/methane jets in crossflows under engine-relevant conditions
… fuel injection strategies, the jet in crossflow (JICF) presents a promising configuration for hydrogen in gas turbine applications, offering enhanced near-field mixing and favourable flame stabilisation characteristics. While the fundamental fluid dynamics of non-reacting JICF have been …

An experimental study of heated jets in a cross-flow from stacks of various geometries
Heated jets in cross-flow (JICFs) occur in a wide variety of situations in engineering practice and the natural environment. Because many industrial and environmental JICFs involve raised-stack emission, non-circular mouths under the influence of shifting winds, and oftentimes strongly heated jet …

Turbulent Simulations of a Buoyant Jet-in-Crossflow
… of turbulence models for the jet--in--crossflow (JICF) problem. For this reason, a comparison is presented for a standard Reynolds--Averaged Navier--Stokes (RANS) and a hybrid Reynolds--Averaged Navier--Stokes/large eddy simulation (HRLES) turbulence model. The mathematical differences are …

Numerical Investigations of a Pipe Jet With Coil Inserts With and Without Crossflow
… effects on both free jet and jet in crossflow (JICF). It provides new insight into the fundamental physics of swirl-assisted mixing and offers a scalable framework for designing passive devices for jet flows. The study employs a pipe jet with a jet Reynolds number of 8500 based on the jet’s bulk …

Fluidic Jet Turbulence Generators for Deflagration to Detonation Transition in Pulsed Detonation Combustors
… distance while using a single Jet in Cross Flow (JICF). Jets in crossflow, depending on orientation and momentum ratio, can induce two types of flow structures that propagate downstream; vortex filaments and turbulent eddies. Vortex flow structures are coherent rotating columns that can persist …

Digital holography for exploring instabilities and breakup of liquid jets in supersonic crossflows
… studies of liquid jets in supersonic crossflows (JICFs) are critical for understanding combustion in scramjet engines. Exploring these fluid dynamic interactions is not only an important step towards characterizing fundamental liquid breakup properties but also key for improving engine design and …
