Simulation Study of Space Spiral Gas-Liquid Separation Technology

Abstract:

The advantages and disadvantages of the method of separating the liquid from the gas on orbit are analyzed aiming at the propellant resupplying on orbit. A new method named spiral gas-liquid separation is proposed here, which is much simpler and highly efficient. Supposing the hydrazine as the propellant, the flow process of two-phase flow is numerical calculated. The results shows that the separated liquid would acquire higher speed and it would take shorter time for the fluid field to be balanced if the inlet fluid speed is higher with a constant gas-liquid ratio at the inlet. The same would take place if the ratio of the liquid to the gas is higher with a constant inlet speed.
