摘要
提供了一种在大口径激波管中降低2区气流雷诺数的方法。采用该方法雷诺数可由通常的10~6～10~7量级降至工10~5量级。实验结果表明采用此方法后2区流场未受明显扰动。给出了驱动压比 P_41与主激波马赫数 M_S1间关系式并由实验加以验证。
A method is provided in the paper for lowering theReynolds number of 2 region in shock tube with larger inner diameter.Using the method,Reynolds number can fall from 10~6～10~7 in general to10~5 order of magnitude.The experimental results show that the flowfield of 2 region in shock tube does not be evidently interfered byemployed the method.The relation between pressure ratio p_(41) and mainMach number M_(51) is given and verified by experiments in the paper.
