Review of closed drift thruster neutral flow dynamics

نویسندگان

چکیده

Operation of closed drift thruster (CDT) relies mainly on neutral gas, whose trajectory and distribution in the flow field have a significant influence performance. Neutral dynamics (NFD), also known as gas thruster, has received increased attention from researchers over past century, drawing to its CDT. This article will therefore review most recent research NFD At outset review, we provide quick overview how CDT works performance, focusing effect CDT’s discharge characteristics oscillations. The distributor channel layout performance is highlighted major portion article. Following that, an typical detection techniques. Additional sub-categories work are provided outside main portion, including usual temperatures, uniformity, types.

Neutral Flow Evolution in a Six-Kilowatt Hall Thruster

Laser-induced fluorescence velocimetry measurements obtained from the interior of a 6-kW Hall thruster using the Xe I 6s 3=2 02 ! 6p 3=2 2 transition at 823.4 nm (vacuum) and the Xe I 6s0 1=2 01 ! 6p0 3=2 2 transition at 834.9 nm (vacuum) are presented. The thruster is operated under seven conditions, with discharge voltages ranging from 150 to 600 V and anode mass flow rates ranging from 10 to...

Drift wave-zonal flow dynamics

A remarkable phenomenon in turbulent flows is the spontaneous emergence of coherent large spatial scale zonal jets. Geophysical examples of this phenomenon include the Jovian banded winds and the Earth’s polar front jet. In this work a comprehensive theory for the interaction of jets with turbulence, Stochastic Structural Stability Theory, is applied to the problem of understanding the formatio...

Computation of Neutral Gas Flow From a Hall Thruster Into a Vacuum Chamber

The finite pressure present in vacuum chamber testing of space propulsion systems such as Hall thrusters can have a number of undesirable effects. For example, the thrust generated by the thruster is higher and the plume divergence angle larger in ground tests in comparison to space operation. To try to quantify these effects, the direct simulation Monte Carlo method is applied to model a cold ...

Modeling of Neutral Entrainment in an FRC Thruster

Neutral entrainment in a field reversed configuration thruster is modeled numerically with an implicit PIC code extended to include thermal and chemical interactions between plasma and neutral particles. The contribution of charge exchange and electron impact ionization reactions is analyzed, and the sensitivity of the entrainment efficiency to the plasmoid translation velocity and neutral dens...

A Review of Hall Thruster Plume Modeling

Hall thrusters are an attractive form of electric propulsion that are being cleveloped to replace chemical systems for many on orbit propulsion tasks on communications satellites. A major concern in the use of these devices is the possible damage their plumes may cause to the host spacecraft. In this paper, the present status of computer modeling of Hall thruster plumes is reviewed in the conte...
