Abstract
Self-excited vibration called the combustion vibration occurs in the combustion apparatus. The vibration and noise adversely affect combustion apparatuses. Therefore it is necessary to control the generation of vibration. But the mechanism of the onset of vibration has not been sufficiently elucidated and countermeasures have not been established. The purpose of our research is to analyze the mechanism of generating the combustion vibration using a cellular automaton method (abbrev. CA). Since a combustion apparatus is in three-dimensions it is difficult to analyze. In this study we analyzed the combustion vibration with a Rijke tube which can be treated in a one-dimensional model. At first, We established the rule of the CA method. In addition, we developed a calculation model using CA method. As a result, we was able to confirm a state of the self-excitation vibration.But it became a different result from the actual experiment.In addition,I suggested that I used perforated plate as a vibration reduction plan.Using the experimental result,the parameters of the perforated plate were determined.We will conduct experiments in the future and confirm the sound abcorbing effect.
