| Abstract: | A numerical model is established for a continuous-wave laser-sustained plasma thruster which takes into consideration the chemical reactions,high-temperature thermodynamic properties,viscosity,diffusion,heat conduction and the effect of radiation on the thruster.The compressible axisymmetric Navier-Stokes equations are solved by pressure-based SIMPLEC algorithm.Given the same chamber pressure,beam focusing geometry and nozzle configuration,the specific impulses with argon propellant for different laser powe... |
