Burning velocity of premixed turbulent flames in the weakly wrinkled regime
, 2005 PhDTurbulent burning velocities have been measured for methane/air and ethylene/air planar flames stabilised in a wide-angled conical diffuser where the flow is decelerated axially.

Energy Science &Engineering, EarlyView.ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Energy Science &Engineering, EarlyView.The proposed hybrid osprey‐salp swarm optimization algorithm addresses optimal power flow (OPF) problems in smart grids incorporating solar, hydro, and thermal generators. The algorithm is validated on Institute of Electrical and Electronics Engineers 30‐, 57‐, and 118‐bus test systems across five single and multiobjective OPF scenarios.

Turbulent flame propagation and combustion in spark ignition engines
, 1983 Pressure measurements synchronized with high-speed motion picture records of flame propagation have been made in a transparent piston engine. The data show that the initial expansion speed of the flame front is close to that of a laminar flame.

Energy Science &Engineering, EarlyView.This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

A thin front model applied to flame propagation in tubes
, 1998 Velocities of stationary curved flames propagating in tubes with ideally adiabatic and slip walls are studied in the model of a thin flame front. It is found that for a tube width larger than some critical value a flame front acquires a curved shape and ...

Exploration, EarlyView.Developing strong and sustainable materials is essential for reducing reliance on metals and lowering carbon emissions. Inspired by how plants naturally harden their cell walls, we created a rapid process that transforms bamboo into an ultra‐hard structural material by rebuilding lignin‐like networks within its structure.
