本文对圆柱和球形水介质内爆的产生过程进行了数值和自相似分析。分析了内爆波与氘氚混合靶的后续相互作用。结果发现，建立的收敛累积水流是自相似的，尽管隐含的状态方程的复杂性。理想化模型的计算结果表明，在水层外半径为7.5mm，总沉积能量为1.35kJ的球形结构下，在1.5ns的时间内可以获得1.5× 10 ~（14）的中子产额。结果表明，水介质中氘氚靶的内爆点火是一种很有前途的惯性约束聚变方法。
A numerical and self-similar analysis of the generation of implosion in water medium in cylindrical and spherical geometries is presented. The following interaction of the implosion wave with a deuterium-tritium mixture target is analyzed. It was found that the established converging cumulative water flow is self-similar, in spite of the complexity of the implied equations of state. Results of an idealized model indicate that, using a spherical geometry setup with 7.5mm external radius of the water layer and ∼35kJ total deposited energy, a ∼1.5×1014 neutron yield during ∼1.5ns time can be achieved. The obtained results suggest that ignition of deuterium-tritium target by implosion in water medium can be considered as a promising method for inertial confinement fusion.
