 note = {本報においては超音速(M=2)における単独円柱および2本の平行な円柱の周りの衝撃波面の解析を行なった.衝撃波面はSchlieren写真法によって得られたものである.波面の頂点を原点にとり,流れの方向にX,それと直角の方向にY軸をとる.円柱の直径を長さの単位に選ぶことによって,長さを無次元化してある.するとX=AY^nの型の方程式において,A,nに適当な値を与えることによって,すべての衝撃波面を,ある有限の領域にわたり,高い近似度をもって表現しうる.単独円柱の場合はA=0.207,n=1.70,離れ距離Δ=0.64である.円柱列の場合はA=0.116-0.0603(H')^<0.67>, n=3.65-1.15(2.5-H')^<0.50>, Δ=1.46-0.20H', 0<H'<2.5という関係がなりたつ.ここでH'は2本の円柱の最短距離である.最後に衝撃波面の頂点付近の曲率半径および,2つの衝撃波の干渉に関する理論的考察を行なった., In this paper are described the analyses of shock envelopes about single circular cylinder and lattices of two parallel circular cylinders in supersonic flow of Mach number 2 based on the experiments reported previously. The vertices of the envelopes are taken as origin, the direction of uniform flow as X co-ordinate, the perpendicular to it as Y, the diameter of the cylinder as unit of length. It is found the formula X=AY^n gives adequate expression for every shock envelope in a limited domain, where A and n are constants defined by experimental data. For single cylinder A=0.207, n=1.70, and Δ (the detachment distance)=0.64. For lattices, the following equations are applicable: A=0.116-0.0603(H')^<0.67>, n=3.65-1.15(2.5-H')^<0.50>, Δ=1.46-0.20H', 0<H'<2.5, where H' is the shortest distance between the surfaces of two cylinders. Furthermore, the radius of curvature in the vicinity of the vertex of shock envelope and the intersection of two shock waves are considered theoretically., 資料番号: SA4148579000},
