Abstract:
Theoretical analysis and experimental study ate performed for droplet evaporation with pressure oscillation.The results show that pressure oscillation makes lnass fraction of vapor OS— cillate in the boundary layer around droplet,which produces oscillation of evaporation rate COIl— trolled by diffusion.Furthermore,the non-equilibrium force brought by pressure decline drives the vapor in the boundary layer flowing into the gas field,and the maximum of evaporation rate exists in the process of pressure decline.The results of experimental study agree well with that of theoreti— cal analysis.
