| Abstract: |
| The existing reactive flow Lagrangian analysis methods are still inadequate when measured the particle velocity records from a series of gauges embedded in material.Based on this point,a new reactive flow Lagrangian analysis method combined the inverse analysis with self-consistency examination is presented.The theoretical accuracy of the method met the self-consistency examination can achieve M-order partial derivatives equal to zero.Besides,the verification of the method for shock to detonation transition (SDT) is studied by a set of test data of small scale gap tests (SSGT).Compared the method,experiment and the traditional inverse analysis results,it not only reduced the accidental error of particle-line,but also makes the particle-line function to reflect the behavior of the various physical quantities along the particle-line. |
