Simplified Numerical Method for the Development of the Inner Flow of Laser Propulsion with Water Propellant

摘要

It is very complex to calculate the development of the inner flow of laser propulsion with a water propellant, which involves mass transfer, heat diffusion, chemical reactions, turbulent current and two-phase flow. If we consider the process of droplet injection with unstable numbers of about tens of milliseconds, several days will be spent completing the calculation. The source of dispersion phase, which takes most of the calculation time has a detrimental effect on the whole calculation. The correlated parameters can be made good by initializing a flow field in a certain error range and the computational efficiency is thereby increased greatly.
