Energy Aspects in Spray Formation by Homogenous Flash Boiling Process
[EN] When a pressurized bubbly mixture is driven out through an orifice, the mixture pressure abruptly drops and the
bubbles undergo a rapid expansion process, which under some circumstances results in a rapid disintegration of
the liquid bulk into small droplets (atomization). Depending on the initial conditions, heterogeneous or
homogeneous nucleation of vapor bubbles may occur. For homogeneous nucleation, the vapor bubbles grow
rapidly one towards the other, and when they touch each other the bubbles “explode”. In this stage, the liquid
around the bubbles is teared, and a spray with small and uniform droplets is formed. In the literature, it seems that
the efficiency of the homogenous flash boiling process is very low. In this work, we analyse this process and
analyse it for possible energy losses.Moshkovich, Y.; Levy, Y.; Sher, I.; Sher, E. (2017). Energy Aspects in Spray Formation by Homogenous Flash Boiling Process.
