Title: Mass Transfer Calculations for Water Vapor

Abstract

In the materials development program for Project Pluto, one of the important properties is corrosion resistance of BeO at elevated temperatures. To investigate this, Saul and Potter have computed corrosion rates for two conditions: (A) equilibrium and (B) finite reaction rates. However, they assume sufficient water is present on the surface so that the reaction may proceed at the prescribed reaction rate. In order to further investigate this condition, calculations were made of the mass transfer rate of water vapor through the boundary layer. This should give an indication as to which process is limiting, the mass transfer rate or the reaction rate. The results of the mass transfer calculations are presented assuming the water vapor reacts with BeO to form Be(OH)2.
