【 摘 要 】

Formation and evolution of pressure waves on the barrier were numerically simulated at non-staionary outflow of the superheated vapor from the vessel. The simulation conditions were fully consistent with the experimental conditions (1982) [1]. The calculated pressure fields were calculated both at the initial stage of non-stationary vapor outflow and at the quasistationary flow of superheated vapor on the barrier. The dynamics of interaction between shock waves and vortex structures on the barrier was studied at quasi-stationary outflow of the superheated vapor, and the experimental pressure profile on the target was compared with the calculated pressure profile. Comparison of the experimental data and the calculation results has showed acceptable agreement between the pressure profiles on the target up to a distance from the target to the nozzle approximately X/D = 6.
