Fluid dynamics and liquid-phase mass transfer in a Brauer gas exchange machine designed for use in spacecraft
Abstract
A comprehensive study of fluid dynamics and gas exchange in three Brauer gas-exchange machines with different geometrical designs is presented. The rotational speed, gas and fluid loading, blade separation, step number, and blade diameter, and gas flow direction were varied. Diffusing air, water, and CO2 served as material components. The gas and fluid flows were determined along with the pressure drop of the gas flow in the machine. The desorption of CO2 from water in the air was used to measure the gas exchange. The high-volume gas exchange capability of this machine is greater than that of any other known machine.
