Laminar flame speeds of stratified methane, propane, and n-heptane flames [PDF]
Combustion and Flame, 2017 Abstract A numerical study on stratified flames of three hydrocarbon fuels, i.e., methane, propane and n-heptane, is conducted using a unsteady, compressible and reacting flow solver ASURF-Parallel. For each fuel, both fuel consumption speeds and flame front propagation speeds of a rich-to-lean stratified flame are compared to those of their ...

The Flame Characteristics of Diesel Fuel Blend with Kepuh (Sterculia Foetida) Biodiesel
Journal of Mechanical Engineering Science and Technology, 2019 Kepuh biodiesel fuel (sterculia foetida) is an alternative fuel that can be used to replace fossil fuel. Diesel fuel is performed to determine the laminar flame speed of combustion and high flame by adding biodiesel kepuh volume of 10%, 20%, 30%.

Angewandte Chemie, EarlyView.We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Extrapolation of laminar flame speeds from stretched flames: Role of finite flame thickness [PDF]
Proceedings of the Combustion Institute, 2017 Abstract Recognizing the persistent inaccuracy of existing linear and nonlinear expressions to extract laminar flame speeds from experimental data of stretched flame speeds, and the essential and independent role of the flame thickness, in addition to the laminar flame speed, in describing the coupled diffusive and reactive response of the laminar ...

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology
Advanced Materials Technologies, EarlyView.The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.
