The purpose of the present is to report a contraction coefficient of a two-dimensional thick orifice for compressible flows. 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.
