Modeling and Numerical Simulation of Arcjet Thrusters.

Development of Optical Diagnostics for Performance Evaluation of Arcjet Thrusters

This paper describes a detailed comparison of experimentally measured arcjet plume properties tomodel predictions. The experiments focus on the measurement of the exit plane vector velocity fieldand kinetic temperature by laser induced fluorescence. The model is based on a single-fluidmagnetohydrodynamic description of the flow. Reasonable agreement between model predictions and...

Simulation of Electric Propulsion Thrusters

Electric propulsion thrusters are replacing small chemical thrusters used for spacecraft control and orbital maneuvers. These thrusters use a variety of mechanisms to convert electrical power into thrust and in general provide superior specific impulse in comparison to chemical systems. Electric propulsion has been under development for the last fifty years, and almost all thrusters are designe...

Multiscale Modeling of Hall Thrusters

Multiscale Modeling of Hall Thrusters Hall thrusters are efficient space propulsion devices that produce thrust by accelerating quasineutral plasma. The thruster consists of a channel with one end open to the ambient environment. The neutral propellant is injected at the closed end and is ionized by electrons produced by an externally mounted cathode. A radial magnetic field is applied across t...

Numerical Modeling and Simulation of Highly Preheated and Diluted Air Combustion Furnaces

This paper presents some of the results of the modeling and simulation of an industrial furnace under the conventional combustion as well as under the highly preheated and diluted air combustion (HPDAC) conditions. The results are obtained using a computer program written by authors in FORTRAN language. It was found that, the HPDAC offers a more uniform and relatively moderate gas temperature p...
