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%.

Hydrodynamic effects induced by nanosecond sparks in air and air/fuel mixtures [PDF]

55th AIAA Aerospace Sciences Meeting, 2017
It was found that short and intense energy release in nanosecond sparks can induce hydrodynamic motion of the gas over a long distance of the order of centimeter. The gas motion induces the transport of active species produced by plasma into the surrounding space.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
