Abstract and Keywords

Abstract: This paper studies the coupled oscillation of two groups of identical candle flames. The relationship between the coupled oscillation of candle flame and the factors such as distance and diameter is obtained by high speed camera and image processing with Origin software. By using MATLAB software and schlieren method, this paper discusses the effects of thermal radiation and thermal convection in the coupling of candles, and it is proved that thermal convection is the dominant factor for the coupled oscillation of candles. Based on the theory of vortex dynamics, the mechanism of coupled oscillation of candle flame is further explained, which provides a theoretical basis for the study of coupled oscillation of candle flame.

Keywords: candle flame; coupled oscillation; thermal radiation; thermal convection; theory of vortex dynamics
