Heat and mass transfer with liquid evaporation into a turbulent air stream

Abstract

Several recent experiments demonstrated the enhancement of turbulent heat transfer with evaporation as compared with that of a dry body. The present study was an attempt to obtain more accurate data on the heat and mass transfer coefficients with water evaporation. In addition, a method of error evaluation was developed and applied to correct the experimental errors in the recently reported results. Most of the corrected values and the present experimental data revealed that the heat transfer coefficient with evaporation agreed with that of the dry body without evaporation within experimental error.
