Abstract

The naphthalene sublimation technique was used to determine the rate of mass transfer from three solid naphthalene cylinders in a natural convection environment. The cylinders’ diameters measured 1, 1.5, and 2 inches nominally, and sublimation rates were found to be 1.42 x 10 -8, 1.89 x 10-8, and 2.28 x 10 -8 kg/s, respectively. The mass transfer coefficients were determined to be 1.64 x 10-3, 1.45 x 10-3, and 1.31 x 10 -3 respectively. Correlations were developed for the Sherwood vs. Rayleigh numbers, Sherwood vs. Grashof numbers, and mass transfer coefficient vs. diameter.
