Burning velocity of premixed turbulent flames in the weakly wrinkled regime [PDF]
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.

Equivolumetric Evolution of Planar Curves
We present the equivolumetric evolution of planar curves, which is a new type of curvature dependent evolution for a flame propagation model. This evolution reflects the nonlinear contribution of the curvature of the front to the flame propagation speed.

Roles of displacement speed on evolution of flame surface density for different turbulent intensities and Lewis numbers in turbulent premixed combustion [PDF]
Direct numerical simulations (DNS) are conducted in 3D to investigate the evolution of flame surface density (FSD) in turbulent premixed combustion. A parametric study is per-formed with respect to turbulent intensity and Lewis number to investigate all ...

Propagation behaviors of twin premixed methane flame in a counterflow annular slot-burner under DC electric fields [PDF]
Under an electric field, hydrocarbon flames generate bidirectional ionic wind due to the movement of positive and negative ions to the cathode and the anode, respectively.

Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...
