Summary

RESULTS OF EXPERIMENTAL INVESTIGATION OF A LIQUID NITROGEN DROPLET EVAPORATING INTO A FLOW OF CARBON DIOXIDE, HELIUM, NITROGEN AND WATER VAPOUR AND OF A DIETHYL ETHER DROPLET EVAPORATING INTO A FLOW OF WATER VAPOUR AT ATMOSPHERIC PRESSURE ARE REPORTED. THE GAS FLOW TEMPERATURE VARIED FROM 293 TO 673 K (20 TO 400.C). THE REYNOLDS NUMBERS RANGED FROM 3 TO 600, THE PRANDTL NUMBERS, FROM 0.3 TO 1.0 AND THE HEAT-AND MASS-TRANSFER PARAMETER, FROM 1.5 TO 15. BOTH VOLUMETRIC AND SURFACE CONDENSATION OF THE AMBIENT GAS HAVE BEEN DETECTED. IN THE CASE OF VOLUMETRIC CONDENSATION THE HEAT-TRANSFER RATE DESCRIBED BY THE STANTON NUMBER IS RELATED TO THE PECLET AND PRANDTL NUMBERS AND THE HEAT-AND MASS-TRANSFER PARAMETER.A CONCLUSION HAS BEEN MADE THAT HEAT AND MASS TRANSFER IS THE PROCESS WHICH LIMITS VOLUMETRIC CONDENSATION.
