The Flame Characteristics of Diesel Fuel Blend with Kepuh (Sterculia Foetida) Biodiesel

open access: yesJournal 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%.

Turbulent Flames Speeds and Laminar Burning Velocities of Dusts using the ISO 1 m3 Dust Explosion Method

open access: yesChemical Engineering Transactions, 2014
The ISO 1 m3 dust explosion vessel was instrumented with thermocouples acting as flame detectors. These were used with methane/air gas explosions to show that the explosion flame was spherical in the constant pressure phase of the explosion and that a ...

Fundamental studies of combustion of droplet and vapour mixtures [PDF]

open access: yes, 2010
There are few experimental data of a fundamental nature that clearly demonstrate the similarities and differences in burning rates between single phase and two phase combustion, either in laminar or turbulent conditions. Such data are essential towards a
