Surface Contamination, Rejuvenation, and the Reproducibility of Results in Nucleate Pool Boiling

Abstract

Contamination of stainless steel boiling surfaces at nucleation sites by corrosion products in water, and by oxide deposits in methanol are investigated experimentally. Reproducibility of boiling data is achieved by nitrogen sparging of test liquids and employing inert components in the apparatus. Heating surface rejuvenation is effected by boiling in refrigerant R-113. The order of testing a surface with various liquids is investigated.
