SPECIES-CONTROLLED CONDENSATION IN ENCLOSURES

ABSTRACT

When noncondensable gases or binary mixtures are present in condensing systems, mass diffusion can provide the dominate heat transfer resistance, giving rise to species-controlled condensation. Current technologies typically attempt to minimize mass diffusion effects by isolating and purging noncondensables away from condensing surfaces. Increasingly, future technologies will apply noncondensables for controlling condensing pressures, and apply binary mixtures to obtain condensation at spatially varying temperatures. In all these problems, accurate analysis of species transport and distribution is critical for predicting condenser performance. This chapter focuses on the physical phenomena which occur during species-controlled condensation in enclosures, by first examining experimental measurements, then covering the techniques and simplifying assumptions available for analysis, and finally discussing applications to several areas of current interest.
