Convective Heat Transfer to Turbulent Droplet Flow in Circular Tubes

Abstract

Turbulent droplet flow heat transfer is analyzed for the thermal entrance region of a circular tube. Calculations are performed considering droplet size variation, vapor acceleration and dilution of droplet number density until the single-phase fully developed conditions is reached. Effect of the relevant dimensionless groups on the heat transfer results is studied. The analytical results are compared with the available experimental data. These comparisons show good agreement between the experimental data and the predictions.
