<p>Resonance behavior of twin flickering (non-premixed) flames at various separation distances horizontally is examined and two oscillation modes (in-phase and anti-phase) are clearly identified depending on the distance. Our ultimate goal is to develop the acceptable mathematical model to explain such resonance behavior. There has been proposed “radiation-basis” mathematical model by physics-oriented researchers, claiming that the radiation is a primary factor to give an anti-phase mode. Our recent experimental and numerical studies, on the other hand, suggest that the radiation may not be the essential factor, rather, fluid dynamical motion shall be a key factor to cause the mode transition. Potential strategy to upgrade the mathematical model are proposed. Taking a “mathematical-scientific” approach to combustion problem is typical inter-disciplinary issue and productive interaction between physicists and combustion researchers is found to be highly recommended to develop further.</p>
