An experimental investigation was performed using a shock tunnel, and the orifice flow was visualized by a color schlieren method. The experimental results show that the compressible flows through an orifice can be classified into three patterns and the contraction coefficient of a thick orifice increases with increase in the length-height ratios., text, application/pdf}, pages = {1785--1788}, title = {圧縮流れに対する厚いオリフィスの縮流係数}, volume = {55}, year = {1989}, yomi = {ヒラハラ, ヒロユキ and ナカノ, ナオヒロ and アオキ, トシユキ and マツオ, カズヤス} }
