Measuring laminar burning velocities

open access: yes, 2016
The laminar burning velocity of a fuel is the rate of normal propagation of a 1D flame front relative to the movement of the unburned gas. This is a fundamental property of a fuel that affects many aspects of its combustion behaviour. Experimental values are required to validate kinetic simulations, and also to provide input for models of flashback ...

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Combustion of a coal char particle in a stream of dry gas.

open access: yes, 2008
The burning rate, surface temperature, drag, and extinction conditions of a single char particle moving in a gas are computed numerically. The effects of the size and velocity of the particle and of the temperature and composition of the gas are examined

IMPACT OF THE NOZZLE ANGLE, DISTANCE BETWEEN BURNERS, AND N2 ON BURNING VELOCITY OF THE DIFFUSOIN COUNTER FLAMES

open access: yesJournal of Engineering and Sustainable Development, 2020
The achievement of precise measurements on the laminar diffusion flames plays a big role in the process of realizing a wide flames range. Despite most of fuel is likely burnt in the turbulent combustion, there is still data requirement for the data on ...
