摘要

本文提出了球形目标等离子体传导区域的准稳态分析模型,并利用该模型分析了激光烧蚀过程中影响质量烧蚀率的因素。与平面几何的情况不同,质量烧蚀率随着到烧蚀前沿的距离增加而变化。对于特定条件下球形目标热传导区域的等离子体,新的分析模型提供了相关参数,如密度、压力和声速,其结果与一维流体力学模拟结果一致。本文介绍的模型和结果是研究激光核聚变过程中质量烧蚀率的宝贵资源。

Analytical derivation and numerical simulation of the ablation rate of a spherical target
This paper presents a quasi-steady-state analytical model of the plasma conduction region of a spherical target, and the model is used to analyze the factors that influence the mass ablation rate during laser ablation. Unlike in the case of planar geometry, the mass ablation rate changes as the distance to the ablation front increases. For the plasma in the heat-conduction region of the spherical target under certain conditions, the new analytical model provides relevant parameters such as the density, pressure, and sound velocity, and its results align with those from one-dimensional hydrodynamic simulations. The model and results presented here are valuable resources for investigating mass ablation rates in laser fusion processes.
