Flame self-interactions in an open turbulent jet spray flame [PDF]
Physics of Fluids, 2021 A three-dimensional direct numerical simulation database of an open turbulent jet spray flame representing a laboratory-scale burner configuration has been analyzed to investigate flame self-interactions (FSIs) in the presence of flow induced shear, to the best of the authors' knowledge, for the first time.

Conditional moment closure modelling of soot formation in turbulent, non-premixed methane and propane flames [PDF]
, 2009 Presented are results obtained from the incorporation of a semi-empirical soot model into a first-order conditional moment closure (CMC) approach to modelling turbulent, non-premixed methane–air and propane–air flames.

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]
, 2010 Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.

Formation of Turbulent Eddies in Jet Diifusion Flames.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1993 The transition from laminar to turbulent modes of an ethylene jet flame was investigated using two-dimensional instantaneous photography of turbulent eddies, by means of a laser-light sheeting method. Observations were made for the eddies around the break point in the fuel flow and the flame. The results show that in the laminar region the fuel flow is

Applications in Energy and Combustion Science, 2023 Flame spray pyrolysis (FSP) is a technique for the synthesis of metal oxide nanoparticles by combusting precursor solutions in a spray flame. The combustion of certain precursor solutions is known to lead to severe droplet disruptions (μ-explosions) in ...

Theoretical Analysis of Nitric Oxide Production in a Methane/Air Turbulent Diffusion Flame [PDF]
, 1980 The coherent flame model is applied to the methane-air turbulent diffusion flame with the objective of describing the production of nitric oxide. The example of a circular jet of methane discharging into a stationary air atmosphere is used to illustrate ...

Effect of CO2 Dilution on the Structure and Emissions from Turbulent, Non-premixed Methane-Air Jet Flames [PDF]
, 2017 This investigation gives a comparison of the variation of temperature and gas compositions in lifted, turbulent non-premixed methane–air jet flames firing vertically into still air with different carbon dioxide diluent concentrations in the fuel jet. The

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain
Advanced Science, EarlyView.OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.
