Abstract: The average Sherwood number as a function of the Reynolds number was determined experimentally for a sublimating cylinder exposed to a cross-flow of air. The sublimation technique was used to obtain the mass transferred from the cylinder to the air. The test cylinder was fabricated of either naphthalene or p-dichlorobenzene. The resultant body of experimental data was characterized by the expression Sh = 0·278Re0·628 with a correlation coefficient of 0·99. The Schmidt number Sc was assumed to be constant for each chemical. Uncertainty analysis indicated that the experimental value of the Sherwood number lay within 9·7% of the true value. The Sherwood number ranged from 55 to 600 for a Reynolds number range of 4720-160000.
