Innovative Transverse Jet Interaction Arrangements in Supersonic Crossflow
… on the premise that adding an array of auxiliary jets behind a main jet injector would alleviate the large region of low pressure typically found downstream of a normal, sonic injector in supersonic flow and also possibly increase in intensity of the upstream high-pressure region. The secondary …

experimental investigation of a reacting transverse jet in a high pressure oscillating vitiated crossflow
Staged combustion is one design approach in a gas turbine engine to reduce pollutant emission levels. In axially staged combustion, portions of the air and fuel are injected downstream of a lean premixed low NOx primary combustion zone. The gas residence time at elevated temperatures is decreased …

Vorticity structure and evolution in a transverse jet with new algorithms for scalable particle simulation
Transverse jets arise in many applications, including propulsion, effluent dispersion, oil field flows, V/STOL aerodynamics, and drug delivery. Furthermore, they exemplify flows dominated by coherent structures that cascade into smaller scales, a source of many current challenges in fluid dynamics. …

Flow characteristics of a transverse water jet into an unconfined water channel
The flow pattern of a transverse jet in a crossflow is complex due to the interaction between the jet and the crossflow. This interaction plays a significant role in practical fluid mixing including effluent discharge in water, film cooling and chemical mixing chamber. In this research, the flow …

Hybrid Eulerian/Lagrangian 3D methods for high Reynolds number reactive flows
… the numerical simulation of turbulent reactive jet flows through the design of a hybrid Eulerian/Lagrangian and massively parallel 3D numerical simulation tool. The adaptivity of the resulting software yields truly fast and accurate simulations, and a better understanding of the simulated …

Lagrangian simulation of transverse jets with a distribution-based diffusion scheme
Transverse jets form a dominant group of flow fields arising in many applications of modern energy utilization, including propulsion and effluent dispersion. Furthermore, they form canonical examples where the flow field is dominated by large-scale and small-scale vortical structures, whose …

Structure and Dynamics of a Reacting Jet Injected into a Vitiated Crossflow in a Staged Combustion System
… minimal contribution to NOx emission. A reacting jet issuing into a high pressure vitiated cross flow operating at gas turbine relevant conditions was investigated as a means of secondary injection. In this application rapid mixing and chemical reaction in the near field of jet injection is …

Fundamental physics and application of plasma actuators for high-speed flows
… by laser energy was also applied to a sonic transverse jet in a supersonic cross flow. Lastly, the particle image velocimetry diagnostic was considered and a technique developed to evaluate measurement uncertainty and using experimental velocity data to solve for density from the continuity …
