RISCarbon and Hydrocarbon Particle Seeding in Air-Breathing Rotating Detonation Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within the power generation community, the rotating detonation engine (RDE) is only growing in popularity with its increased performance, simple mechanism, and operation. Although significant testing is underway to ...
Modal Analysis of Breakup Mechanisms for a Liquid Jet in Crossflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid fuel jet in crossflow (LJIC) is a vital atomization technique significant to the aviation industry. The hydrodynamic instability mechanisms that drive a primary breakup of a transverse jet are investigated using ...
The Effect of Pressure on NOx Entitlement and Reaction Timescales in a Premixed Axial Jet-In-Crossflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the pressure dependency of a lean premixed jet injected into a lean vitiated crossflow with an experimentally verified detailed chemistry computational fluid dynamics (CFD) model and 53 species ...
Fuel Stratification Influence on NOx Emission in a Premixed Axial Reacting Jet-in-Crossflow at High Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three reacting jet-in-crossflow (JiC) methane/air flames were numerically investigated in a lean axially staged combustor at a pressure of five atmospheres. A detailed chemistry Star-CCM+ computational fluid dynamics (CFD) ...
Flow-Independent Liquid Jet-in-Crossflow Injection Using Physical Obstructions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work explores a novel flow-independent liquid injection scheme, incorporating solid obstructions to alter the key mechanisms controlling the liquid breakup and trajectory. These obstructions, designated pintiles, ...
Partial Premixing Effects on the Reacting Jet of a High-Pressure Axially Staged Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of partial premixing on a reacting jet-in-crossflow is investigated in a five atmosphere axially staged combustor at stationary gas turbine relevant conditions. The facility consists of a dump style headend ...
Shock Tube Demonstration of Acousto-Optically Modulated Quantum Cascade Laser as a Broadband, Time-Resolved Combustion Diagnostic
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We provide the first demonstration of an acousto-optically modulated quantum cascade laser (AOM QCL) system as a diagnostic for combustion by measuring nitric oxide (NO), a highly regulated emission produced in gas turbines. ...
On the Influence of Fuel Distribution on the Flame Structure of Bluff Body Stabilized Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes recent learning on the flame structure associated with bluffbody stabilized flames and the influence of the fuel distribution with nonpremixed, jetincrossflow fuel injection. Recent experimental and ...
Simulation of Premixed and Partially Premixed Jet-in-Crossflow Flames at High Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we explore the operational map of a lean axial-staged combustor of premixed and partially premixed reacting jet-in-crossflow flames at high -pressure (5 atm). This study attempts to expand the data to ...
