Dynamical mode recognition of triple flickering buoyant diffusion flames in Wasserstein space

Structure of Overfire Soot in Buoyant Turbulent Diffusion Flames at Long Residence Times

The structure of soot was investigated within the fuel-lean (overfire) region of overventilated buoyant turbulent diffusion flames burning in still air. The study was limited to the long residence time regime where characteristic flame residence times are roughly more than an order of magnitude longer than the laminar smoke point residence time and soot generation factors (the mass of soot emit...

Experimental Investigation of the Velocity Field in Buoyant Diffusion Flames Using PIV and TPIV Algorithm

Synchronization in flickering of three-coupled candle flames

When two or more candle flames are fused by approaching them together, the resulting large flame often exhibits flickering, i.e., prolonged high-frequency oscillation in its size and luminance. In the present work, we investigate the collective behaviour of three-coupled candle flame oscillators in a triangular arrangement. The system showed four distinct types of syncronised modes as a consequ...

AlAA 94-0428 Soot Nucleation and Growth in Weakly-Buoyant Laminar Jet Diffusion Flames

Chemiluminescent Oh* and Ch* Flame Structure and Aerodynamic Scaling of Weakly Buoyant, Nearly Spherical Diffusion Flames

Normal-gravity experiments were conducted with inverse diffusion flames of small density difference with their surrounding ambient to study low Grashof number (Gr) flames that were several centimeters in diameter. The intensity of buoyancy was minimized by ejecting diluted air from a porous, spherical burner into a lower-density fuel atmosphere of hydrogen or hydrogen and methane at reduced pre...
