The Flow due to Impulsive Motion of a Wedge and its Similarity to the Diffraction of Shock Waves

抄録

After some general discussion, an analysis is performed to clarify the non-uniform region of the air flow caused by impulsive motion of a wedge with small vertex angle. It is shown that the present problem is quite similar to the well-known problem of the interaction of a shock wave and the wedge. By use of this similarity, some cases of wedges having not small vertex angles are discussed.
