Abstract

The paper describes a method for generating aluminum and hydrogen plasma jets. It illustrates the formation mechanism of extended plasma structures produced during the combustion of a high-current vacuum-arc discharge. The current-carrying plasma front is shown to propagate at different velocities for aluminum plasma and hydrogen plasma. The hydrogen plasma has a substantially higher initial velocity (about 30 cm/µs) compared to the aluminum plasma (about 10 cm/µs). It is shown that the bulk velocity of the hydrogen plasma jet is about 9 cm/µs. It was proven by means of spectral diagnostics that the hydrogen plasma jet is indeed composed mainly of hydrogen.

大电流真空弧放电燃烧过程中定向等离子体射流的形成

摘要本文介绍了一种产生铝和氢等离子体射流的方法。它说明了大电流真空电弧放电燃烧过程中产生的扩展等离子体结构的形成机理。铝等离子体和氢等离子体的载流等离子体前沿以不同的速度传播。与铝等离子体（约 10 cm/µs）相比，氢等离子体的初始速度要高得多（约 30 cm/µs）。研究表明，氢等离子体射流的整体速度约为 9 cm/µs。通过光谱诊断证明，氢等离子体射流确实主要由氢组成。
