Analysis of Burning Candle

J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer
AltaSim Technologies LLC, Columbus, OH, USA

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... Читать дальше

Classical Models of the Interface Between an Electrode and an Electrolyte
