「炎の歌を聞く8月の杜若」を語る --2022年優秀作品賞受賞作品--

Abstract

A story of making "August iris flower listening to the song of flame" were described. The photo is composed by two main components of a laminar diffusion flame array formed on a Rubens tube and dielectric barrier discharge (DBD) on iris flower. The different frequency of sinuous wave was applied to the speaker attached at the end of tube for controlling heights of the laminar diffusion flame array and the waveform appeared on the Rubens tube. The frequencies of sound wave varied from 400 Hz to 900 Hz. DBD on iris flower was achieved to express a situation that the flower is listening the songs of flames. Electrodes for the DBD were the iris flower itself and acrylic water tank. The frequency of DBD was set to 7 kHz and its applied voltage was set to 35 kV peak to peak. In the final product of the submission, the flame array was flipped vertically and arranged at the bottom. On the back of the flame array iris flower with DBD were placed to express the pose of listening to the sound of flame.
