| Abstract: | The heating and flow process in a continuous wave laser powered thruster using argon as propellant was modeled numerically.A model of physical mechanisms including laser absorption,chemical reaction,high-temperature thermodynamics properties,viscosity,diffusion,heat conduction and the effect of radiation was built up.The two-dimensional axisymmetric flow filed described by Navier-Stokes equations was solved by pressure-based SIMPLEC(semi-implicit method for pressure-linked equations consistent) algorithm.Th... |
