At subcritical pressures, atomization devices in chemical-propulsion systems must ensure proper rupture of the liquid volume through aerodynamic shearing and homogeneous dispersion of the liquid droplets in the combustion chamber. The gas environment in the combustor is typically hot as a result of the heat released by chemical reactions, with part of its enthalpy being employed in vaporizing t...
