Summary of AHF 348 POCO Graphite Experiment

This document provides a summary of the data products from the POCO graphite Iso-Q run from AHF 348. POCO graphite is an UNCLASSIFIED material, and therefore this experimental dataset is being considered for public release as thermal response code validation exercise.

Hydrogen Desorption and Adsorption Measurements on Graphite Nanofibers

Graphite nanofibers were synthesized and their hydrogen desorption and adsorption properties are reported for 77 and 300 K. Catalysts were made by several different methods including chemical routes, mechanical alloying and gas condensation.

Recent Work at Langley Research Center in the Development of a Graphite-Heated Small-Scale Hypersonic Nitrogen Tunnel

It is the purpose of this paper to discuss the development of and to present some preliminary data results which were obtained during the operation of a high-pressure-high-temperature induction-type heat exchanger. The subjects to be covered are: (1) An overall description of the induction heater and the various graphite elements tested in the heater; (2) Effects of the mass rate of flow on stagnation temperature; (3) Heat-transfer data on one heater element; (4) Effect of power input on gas stagnation temperature, and (5) The evaluation of mass flow technique as a method for determining true gas stagnation temperature.
