Considering real gas effects of the shock wave speed calculation
Factors can be expressed as △ = (. 1,[link widoczny dla zalogowanych],1, D,, y) can be obtained by dimensional analysis the following independent dimensionless quantity, toxicity,[link widoczny dla zalogowanych], Kyrgyzstan, and take the form of shock attenuation: a = ( a 1 )'・()( old) on both sides to take on the effect was: Hangzhou Institute of Applied Engineering Zhu first l1 surgery volume lIL (Bian a MI) = (the wall of a 1) + lnB +1 lll () + n1n (Kyrgyzstan) 3 .2 experimental device (see circle 2) the determination of 3.3 remains the same experiment,[link widoczny dla zalogowanych], the experimental results shown in Figure 3. Port = l3.4n1 fitting a straight line to determine the results of experiments shown in Figure 4. Results of linear fitting to determine I = 0.1833.52 stay on the same experiment can write the two formulas in k () I1nB + n (South) n (Tony) ln () lI1 (ln (seedling) two-type subtraction was a nn () ((beetles) from Table 3 the average results of 2 available, 2 = 1.462283.6 determination to take port = 1,1 = 0.183, / 12 = 1.46 with the public ( ) a + o.83i) +1.461 n (Kyrgyzstan) M, taking the initial Mach number of theoretical calculations, Ms were taken n at.】 lf1 and 2 of the M2, calculate their corresponding BylIBy2, and asked for their average value as the value of the last day ugly: (no 1 + no 2) / 2:4.953 x1n III-3 Figure 2 shake luxuriant attenuation of the experimental setup to determine n 3, the experimental results on a 3 lap 4 the experimental data set to determine n, 1,2 The results of Zhang Jingping,[link widoczny dla zalogowanych], etc.: to consider the real effect of the shock wave velocity of the gas 9 Table 4 the experimental data to determine the application of 3.7 attenuation coefficient was determined to come to a shock wave attenuation in the Co2 \and then out of the% operator to experiment with an attenuation of the shock wave speed position, the maximum relative error of a <1.3%, 5 laboratories in 4 experiments the relative error of 0.65% or less. '10 Hangzhou of Applied Engineering and Technology Volume 4 Conclusion No. ll O-level model, consider the real gas effects can be accurately calculated after the shock of the ductile rupture of membranes before the speed, the shock attenuation of the experimental formula obtained with the theoretical beginning of the shock ductile combination of speed, you can accurately calculate the shock tube at different locations along the shock speed, shock tube design provides an important reference for calibration.
