Construction and Operation of Apparatus for Study of Heat Transfer with Surface Boiling.

摘要

A detailed description of the test apparatus designed and constructed to study the effects of surface boiling on heat transfer at high pressures and high heat flux densities is presented. A discussion is given of operating techniques, data measurements, and calculating procedure with derivations of formulas, calibration of instruments, and other experimental determinations. A series of photographs which record the dismantling of the Hayward-Tyler centrifugal pump for cleaning are presented. They indicate very clearly the source of the contamination which has led to a continual deposition of scale on the inside of the test section, apparently due to an electro-plating of ferric ions. Cleaning of this scale has proven to be exceedingly time consuming and an ion-exchanger to trap the objectionable ions is to be added to the circuit.
