Brief Communications


An approximation of the boundary of the jet within the limits of the first “barrel” of the arc of anellipse is proposed (on the basis of analysis of schlieren-photographs of the stream in the range M a = 1 to 4.85, n=1 to 103, χ=1.3 to 1.67;β=0 to 21°). The results of calculations of the boundary according to the proposed method are compared with results of calculation by a method of characteristics, and with experimental data.
