THE THERMAL TRANSPORT PROPERTIES OF HELIUM, HELIUM-AIR MIXTURES, WATER, AND TUBING STEEL USED IN THE CACHE PROGRAM TO COMPUTE HTGR AUXILIARY HEAT EXCHANGER PERFORMANCE

摘要

This report presents, quantitatively, the thermal transport properties of the materials involved in digital computer calculations of heat transfer rates by the Core Auxiliary Heat Exchangers in large HTGR nuclear steam supply systems. These materials are pure helium, mixtures of helium with com¬mon gases having molecular weights in the range of 28 to 32, alloy steel tubing, and water.nFor use in programmed computations the viscosity, thermal conductivity, and specific heat, are represented primarily by equations augmented by curves and tabulations. Materials supporting the development and selection of the property equations is included.
