An Experimental Investigation of Flame Spreading from Bluff Body Flameholders [PDF]
, 1958 Flame spreading from 1/16 to l inch circular cylinder flame holders in two-dimensional flow was studied experimentally. Combustion wake widths were determined by use of spark Schlieren photographs at distances up to 36 inches downstream of the flame ...

Advanced Materials, EarlyView.Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Nonlinear response of conical flame to dual-frequency excitation
Applications in Energy and Combustion ScienceThis work investigates the nonlinear response of a conical premixed flame to dual-frequency excitation through experiments and G-equation analysis. In addition to the responses at excitation frequencies, f1 and f2, a notable flame response can also be ...
