A rocket plume impinging on the lunar surface when a lunar lander approaches a landing
site can cause significant dust dispersal. This study investigated the near-field rocket plume …

Several hybrid fluid–particle simulations are performed to investigate the plasma plume
flows from a cluster of Hall thrusters. These simulations adopt a detailed fluid electron model …

Fully kinetic particle-in-cell simulations are carried out to study ion acceleration in a
geometrically expanding plasma beam. The ion acceleration is demonstrated to be …

The unsteady process of rarefied jet flows expanding into a vacuum is numerically solved by
the Gas-Kinetic Unified Algorithm (GKUA) based on the Boltzmann model equations. The …

This paper presents comprehensive studies on two closely related problems of high speed
collisionless gaseous jet from a circular exit and impinging on an inclined rectangular flat …

This paper presents a set of gaskinetic solutions to the problem of unsteady collisionless
round plume development: startup and development to a steady flow; steady flow; and …

针对空间站运行过程中可能发生的舱外泄漏, 建立真空环境中气体分子运动的物理模型,
运用直接模拟蒙特卡罗(DSMC) 方法对气体羽流场进行数值模拟, 得到不同条件下的羽流场气体 …

逆向发动机常用于对飞行器进行减速或分离. 为研究高空稀薄条件下逆向发动机喷流和自由来流
的相互作用, 构建了由两个逆向喷流和高超声速自由来流相互干扰形成的稀薄流场 …

This paper presents a numerical model and simulations of a jet flow expelled into a low-
pressure environment and impinging on a smooth wall. The model is used to understand the …

The International Space Station program is developing a robotically-operated leak locator
tool to be used externally. The tool would consist of a Residual Gas Analyzer for partial …
