Numerical Simulations of Multi-Confined Jets in Crossflow at Supercritical Pressure
<p>The objective of this study was to numerically investigate the mixing characteristics of two and three confined jets in crossflow (JICF) at supercritical pressure using K-ℇ and K-ꞷ turbulence models as well as the Large Eddy Simulation (LES) method using Siemens CCM+ software. The JICF has many …

An Experimental Study of Single and Multiple Turbulent Buoyant Jets in Crossflow
The phenomenon of turbulent, buoyant jets in crossflow is a fundamental fluid mechanics problem with many application areas, including jets discharged from natural and mechanical draft cooling towers. Buoyant jets have been studied for many years, and as a result there exists a large body of …

Planar Laser Induced Fluorescence Experiments and Modeling Study of Jets in Crossflow at Various Injection Angles
Planar Laser Induced Fluorescence (PLIF) with acetone seeding was applied to measure the scalar fields of an axisymmetric freejet and an inclined jet-in-crossflow as applicable to film cooling. From the scalar fields, jet-mixing and trajectory characteristics were obtained. In order to validate the …

Large Eddy Simulations of complex turbulent flows
<p>In this dissertation a solution methodology for complex turbulent flows of industrial interests is developed using a combination of Large Eddy Simulation (LES) and Immersed Boundary Method (IBM) concepts. LES is an intermediate approach to turbulence simulation in which the onus of modeling of …

Fluidic Jet Turbulence Generators for Deflagration to Detonation Transition in Pulsed Detonation Combustors
<p>The goal of this study is to establish the dominant flow structure required to effectively accelerate the turbulent deflagration flame front to detonation velocity in the shortest possible distance while using a single Jet in Cross Flow (JICF). Jets in crossflow, depending on orientation and …

Flow and Thermal Field Measurements in a Combustor Simulator Relevant to a Gas Turbine Aero-Engine
The highly competitive gas turbine industry has been motivated by consumer demands for higher power-to-weight ratios, increased thermal efficiencies, and reliability while maintaining affordability. In its continual quest, the industry must continually try to raise the turbine inlet temperature, …
