Abstract

The interaction of collisionless shocks with fully developed plasma turbulence is numerically investigated. Hybrid kinetic simulations, where a turbulent jet is slammed against an oblique shock, are employed to address the role of upstream turbulence on plasma transport. A technique, using coarse graining of the Vlasov equation, is proposed, showing that the particle transport strongly depends on upstream turbulence properties, such as strength and coherency. These results might be relevant for the understanding of acceleration and heating processes in space plasmas.

摘要

对无碰撞激波与充分发展的等离子体湍流之间的相互作用进行了数值研究。采用混合动力学模拟方法,将湍流射流撞击到斜激波上,以研究上游湍流在等离子体输运中的作用。提出了一种使用弗拉索夫方程粗粒化的技术,结果表明粒子输运强烈依赖于上游湍流特性,如强度和相干性。这些结果可能有助于理解空间等离子体中的加速和加热过程。
