    Abstract
  • This article describes the numerical simulation for shock compression which is produced by layered flyers impacting target, in which the isentropic curve is calculated by recurrence method. Take water and tantalum for examples, the calculation results show this kind of flyers can produce good effects of quasi-isentropic compression for water and tantalum, and the result for water is in accord with the reference data, the calculation results for the interface velocity between Ta/LiF is in accord with the experimental results. Therefore, the method to obtain quasi-isentropic compression by layered flyers impacting target and the method of numerical simulation for quasi-isentropic compression are reliable.
