要約

The results of the experimental investigations carried out under the guidance and with the participation of the authors at MSI, VNIIAM, DVPI(USSR) and IFE (Leipzig, DDR) are presented in the report. The influence of small (0,001+0,01%-) octadecylamine (ODA – C18H37NH2) additives on the heat transfer in boiling conditions in a volume, with the single-phase flow on surfaces as well as interphase heat-mass transfer intensification in steam-droplet flows due to droplets crushing are considered. In these cases general cause of additives influence is the change of surface tension of liquid and also its cleaning properties. Some investigation results showing that ODA additives introduction into high-velocity overcooled steam flows intensifies processes of spontaneous condensation and interphase heat-mass transfer are given in conclusion.
