BOS法を用いた加熱壁周りの自然対流境界層可視化の有用性評価

抄録

Background-oriented schlieren (BOS) methods is a non-contact method for visualizing fluid density fields. However, previous studies have not been applied to the visualization of natural convection boundary layers such as those formed on vertically heated walls. In this study, the possibility of the visualizing the density distribution of the natural convection boundary layer around the heating wall using the BOS method was discussed. From the experimental results, the refractive index changes along the heated plate was visualized but the further the adjustment of the camera’s focusing is required.
