Helium Heat Transfer,

Abstract

Publications of the NBS Cryogenic Division relating to helium heat transfer are summarized, and new results from this past year are given in full. In this latter category are included the following: (1) comprehensive review of thermal oscillations and instabilities, including recommendations for needed direction of study, (2) brief summary of the combination of refrigeration systems and cooling loops, (3) analytical study of superconductor stability under forced flow conditions, analogous to previous studies for pool boiling, (4) Kapitza conductance and thermal conductivity measurements on copper, niobium, and aluminum, and (5) tabular data on a variety of helium properties of importance to the cryogenic engineer. In addition, a brief outline is given of work in progress and/or planned for next year, including forced two-phase flow experiments, further Kapitza conductance measurements, possible superfluid forced flow studies, helium pump survey and evaluation, and thermal stability studies on a cryogenic power transmission line.
