Abstract

Three sizes of paradichlorobenzene spheres were cast and allowed to sublimate in a natural convection environment. The mass loss over time was recorded, and a sublimation rate was calculated. The three sphere diameter sizes were: 0.04025 m (1.58 in), 0.0677 m (2.67 in), and 0.0846 m (3.33 in). The Schmidt number was shown to be a constant 3.64 from calculations. Results of experiments show that the range of Sherwood numbers varies from 1.19 × 104 up to 1.71 × 104, and the Rayleigh number climbs from 69.3 to 643.5. An equation was developed to relate these dimensionless numbers.
