Combustion regimes in sequential combustors: Flame propagation and autoignition at elevated temperature and pressure [PDF]

open access: yesarXiv, 2018
This numerical study investigates the combustion modes in the second stage of a sequential combustor at atmospheric and high pressure. The sequential burner (SB) features a mixing section with fuel injection into a hot vitiated crossflow. Depending on the dominant combustion mode, a recirculation zone assists flame anchoring in the combustion chamber ...

New type of microengine using internal combustion of hydrogen and oxygen [PDF]

open access: yesSci. Rep. 4, 4296 (2014), 2014
Microsystems become part of everyday life but their application is restricted by lack of strong and fast motors (actuators) converting energy into motion. For example, widespread internal combustion engines cannot be scaled down because combustion reactions are quenched in a small space.

Non-linear simulations of combustion instabilities with a quasi-1D Navier-Stokes code [PDF]

open access: yes, 2010
As lean premixed combustion systems are more susceptible to combustion instabilities than non-premixed systems, there is an increasing demand for improved numerical design tools that can predict the occurrence of combustion instabilities with high accuracy.

Boosted Thermal Storage Performance of LiOH·H2O by Carbon Nanotubes Isolated Multilayered Graphene Oxide Frames

open access: yesAdvances in Materials Science and Engineering, 2022
Cellulose-originated three-dimensional graphene oxide CNT-modified LiOH·H2O (3D-GO-CNTs-LiOH·H2O) was synthesized by the hydrothermal method. LiOH·H2O nanoparticles (5–50 nm) were homogeneously dispersed inside the 3D-GO-CNTs frames. The composite showed

Snapshot multicolor fluorescence imaging using double multiplexing of excitation and emission on a single detector

open access: yesScientific Reports, 2021
Fluorescence-based multispectral imaging of rapidly moving or dynamic samples requires both fast two-dimensional data acquisition as well as sufficient spectral sensitivity for species separation. As the number of fluorophores in the experiment increases,
