Abstract

The rates of heat and mass transfer from equilibrium non-spherical n-heptane drops in an air stream have been investigated. Two types of drops were produced, one wetting the supporting tube and another not wetting the supporting tube. The drops ranged from 0.005 to 0.008 ft in diameter. Measurements were made at bulk air velocities between 2 and 8 fps, with an air temperature of 100?F. A semi-empirical relation taking into account the deviation of drop shape from spherical leads to a satisfactory correlation of data with those obtained by other investigators for spherical drops.
