Abstract

In this work, radius of shock wave of plasma plume (R) and speed of plasma particles (U) have been calculated theoretically using Matlab program. Both parameters (R and U) were calculated using Sedov-Taylor model in Ar background gas. The effect of laser pulse energy (Es) on radius of shock wave of plasma plume and speed of plasma particles has been investigated in this study. Also the temporal profile of both R and U has been studied. In conclusion, as Es increased, plasma plume shock wave radius (R) and plasma species speed (U) increased. The cylindrical explosion of plasma has been assumed in this study of Sedov-Taylor model.In this work, radius of shock wave of plasma plume (R) and speed of plasma particles (U) have been calculated theoretically using Matlab program. Both parameters (R and U) were calculated using Sedov-Taylor model in Ar background gas. The effect of laser pulse energy (Es) on radius of shock wave of plasma plume and speed of plasma particles has been investigated in this study. Also the temporal profile of both R and U has been studied. In conclusion, as Es increased, plasma plume shock wave radius (R) and plasma species speed (U) increased. The cylindrical explosion of plasma has been assumed in this study of Sedov-Taylor model.

用Sedov-Taylor模型估计等离子体羽流中激波位置

本文利用Matlab程序对等离子体羽流激波半径R和等离子体粒子速度U进行了理论计算。采用Sedov-Taylor模型计算了Ar背景气体中R和U两个参数。研究了激光脉冲能量对等离子体羽流激波半径和等离子体粒子速度的影响。此外，还研究了R和U的时间分布。综上所述，随着Es的增大，等离子体羽流激波半径(R)和等离子体种速(U)增大。在Sedov-Taylor模型的研究中，假设了等离子体的圆柱形爆炸。本文利用Matlab程序对等离子体羽流激波半径R和等离子体粒子速度U进行了理论计算。采用Sedov-Taylor模型计算了Ar背景气体中R和U两个参数。研究了激光脉冲能量对等离子体羽流激波半径和等离子体粒子速度的影响。此外，还研究了R和U的时间分布。综上所述，随着Es的增大，等离子体羽流激波半径(R)和等离子体种速(U)增大。在Sedov-Taylor模型的研究中，假设了等离子体的圆柱形爆炸。
