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 ...

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%.
