Task R

Abstract

Thermal conductivity of gases: High temperature gas thermal conductivity measurements by means of a line source in a laminar flow are being carried out. The theory of the thermal conductivity of binary polyatomic mixtures is outlined. Experimental results on N2, CO2, and N2 - CO2 mixtures are given over a wide temperature range. Rocket nozzle fluid dynamics: Experimental measurement of the flow properties in a rocket nozzle employing a typical solid propellant is discussed. Additional evidence of flow separation near the throat is given. Results of pitot tube boundary layer measurements are presented. Refinements in the IR spectroscopy of the nozzle gas compositions were continued; some spectra are shown. Rocket nozzle chemical kinetics: The purpose of this project is to apply the results of Task R and other research to an analytical study of complex chemical kinetics in the flow of real propellant gases through nozzles. Equations and numerical program for machine calculation are presented.
