论文摘要
呈现了暴露于高血浆热通量和压力梯度的铜阴极表面上熔化和火山口形成的流体动力学模拟。根据先前发布的模拟，对金属内部自由表面的预测变形和金属内部的温度演变进行了基准测试。尽管物理模型完全是流体动力学的，并且忽略了各种等离子表面相互作用过程，但结果也证明与更高级模型的预测以及实验数据非常一致。这为与金属等离子体的瞬时表面熔化和滴落表面熔化和液滴射血的研究提供了合理的基础。
Fluid dynamics simulations of melting and crater formation at the surface of a copper cathode exposed to high plasma heat fluxes and pressure gradients are presented. The predicted deformations of the free surface and the temperature evolution inside the metal are benchmarked against previously published simulations. Despite the physical model being entirely hydrodynamic and ignoring a variety of plasma-surface interaction processes, the results are also shown to be remarkably consistent with the predictions of more advanced models, as well as experimental data. This provides a sound basis for future applications of similar models to studies of transient surface melting and droplet ejection from metallic plasma-facing components after disruptions.
