Abstract

Convective sublimation from a cylinder fixed in a parallel-plate duct has been studied, both theoretically and experimentally. In the theory, a simple and efficient finite difference technique has been developed to solve the Navier-Stokes and diffusion equations. The procedure contains a transformation of the coordinate system to facilitate the treatment for curved boundaries. The calculated results concerning the average Sherwood number are in very close agreement with those of the experiment.
Through a comparison of the results for bounded flow in a duct with those for unbounded flow in an infinite region, it is found that the duct wall tends to depress the development of the wake behind a cylinder, and to promote mass transfer from it.
