Flame Stabilisation Mechanism for Under-Expanded Hydrogen Jets
FireA hydrogen under-expanded jet released from a high-pressure vessel or equipment into the atmosphere through a 0.53 mm diameter orifice results in a sustained lifted flame for pressures above 4 MPa and flame blow-out at pressures below 3 MPa. Knowledge of

Berichte zur Wissenschaftsgeschichte, EarlyView.Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

Soot control of laminar jet-diffusion lifted flame excited by high-frequency acoustic oscillation
Journal of Thermal Science and Technology, 2017 A novel technology to reduce soot is developed utilizing a high-frequency standing wave of 20 kHz applied to a methane-air lifted jet flame base. The amount of soot was measured using the transmitted light attenuation method. A mixing profile of the fuel

Instantaneous flame-stabilization velocities in lifted-jet diffusion flames
Combustion and Flame, 1997 Liftoff height and velocity measurements are presented for turbulent, lifted methane and ethylene flames. A range of Reynolds numbers from 3800 to 22,000 is investigated, and the effect of coflow velocity is examined. The mean liftoff height is shown to increase with jet-exit and coflow velocity, while the rms fluctuation about the mean increases with ...

Effect of pressure on the characteristics of lifted flames [PDF]
Proceedings of the Combustion Institute, 2019 Abstract The effects of pressure on the characteristics of lifted flames in a coflow with propane fuel were investigated experimentally in a pressure chamber. Changing the pressure influenced the density, reaction kinetics, and flame propagation speed. The pressure range tested was P = 0.5–5.5 atm.

Business Strategy and the Environment, EarlyView.ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

ChemFoodChem, EarlyView.Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...

Lifted Partially Premixed Flames in Microgravity [PDF]
42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004 Lifted Double and Triple flames are established in the UIC-NASA Partially Premixed microgravity rig. The flames examined in this paper are established above a coannular burner because its axisymmetric geometry allows for future implementation of other non-intrusive optical diagnostic techniques easily.
