Dryout front modeling for rod bundles

Description

The dryout zone is that region between the calculated pool liquid level and the point where a rod or tube submerged in the pool dries out. A method of calculating the extent of the dryout zone is presented. Recommended values for the drift flux model constants are given for rod bundles. These are needed to make these calculations. For void fractions less than 0.45 at the free surface, the dryout front and the water are level virtually the same. For void fractions above, 0.45, the extent of the dryout front is proportioned to the superficial velocity of the vapor, rising to a value of .3m for a superficial velocity of 2m/s
