To investigate the cause of this phenomenon, oil flow visualization on a new OREX model and a hyperbolic model with smooth front surface at Mach numbers 1.5, 3.0, and 4.0 was conducted. As the Mach number increases, the ring patterns become more clear on the OREX model. The patterns appear along the circular junction line of the spherical and the conical curvatures of the model. No ring pattern was observed on a hyperbolic body of revolution in which the second derivative of the curvature is continuous. By comparing the pressure distributions on the OREX model surface and the ring patterns, it was found that the ring patterns are formed near the junction of two curvatures in which the pressure coefficients change from rapid decreases to slow decreases or to increases downstream. Thus, the ring patterns are laminar boundary layer bubbles on the OREX model caused by unfavorable pressure gradients.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
