Excitation of acoustic vibrations during volume condensation in a steam–gas mixture
Annotation
A theoretical investigation is performed of the acoustic instability under conditions of volume condensation in a steam–gas mixture. The steam–gas mixture is assumed to be stationary and consist of a gas and moist steam. It is assumed that gas and steam are ideal gases and that the condensation process is nonequilibrium. Condensate droplets are assumed to be spherical and monodisperse, and their volume concentration is assumed to be minor compared to unity. It is demonstrated that acoustic vibrations are excited during volume condensation of steam. Formulas are derived for the calculation of the increment and frequency of vibrations.
