Heat and mass transfer under the film condensation from vapour-gas-dust mixtures

摘要

Results of the theoretical and experimental investigations of the film condensation from vapour-gas-dust mixtures have been presented. Main factors which influence the drift of particles of disperse phase to the surface of the condensate film have been investigated by numerical experiment. For the particle located nearby the interface the time of its capture by the liquid film has been evaluated. It is shown that dust component influences the regime of condensation and changes the heat and mass transfer intensities at the initial site of cooled wall.
