The radiation field of a hypersonic nozzle flow
Abstract
This paper discusses features of the spectra observed looking axially towards the throat of a hypersonic nozzle in a shock tunnel assembly. At the throat, the gas is optically opaque, while at the nozzle exit the gas is optically thin. In principle, the radiation field may be controlled by varying the nozzle shape and it may therefore be used for optical modelling of other radiation fields of differing physical dimensions. Requirements for implementing this program are discussed.
