Evaporation level of the condensate droplets on a shock wave in the IMP PAN nozzle depending on the inlet conditions

2016 
In the present paper we have focused on the phenomena of condensate reevaporation in the shock wave zone. Having observed the finishing of a foggy flow within the shock wave, according to Puzyrewski's observations, we would like to analyse the critical inlet conditions which cause total evaporation of condensate droplets on the shock in the IMP PAN nozzle. In the paper some original mechanistic model of droplet evaporation is involved, numerically implemented and compared with the IMP PAN experiment. The single continuum model of wet steam with a special microstructure growing up during phase transitions was validated on IMP PAN experiment performed for inlet conditions close to the saturation line. The present work includes simulations results of total and partial evaporation liquid phase on the shock wave for different boundary conditions.
