Interactions between a Multicomponent Flow and a Laser Beam. Part I. Vaporization of Liquid-Air Droplets by High-Power Laser Beams.

Abstract

The interaction between a high-power laser beam and a moving cloud of vaporizing droplets is considered theoretically. A study was performed to assess partially the feasibility of a new concept of generating an ultra-high-total-enthalpy flow. The spectral absorption coefficient of liquid air was determined at the fundamental vibration-rotation frequencies of liquid nitrogen and oxygen. A perturbation solution was sought for a small arbitrary variation in the velocity of the moving droplets. The first-order correction to uniform-velocity solution has been explicitly carried out in closed form. (Modified author abstract)
