Abstract:An analysis is presented relating the radiation intensity time gradient behind shock waves in air to the shock−wave attenuation rate in a shock tube and boundary−layer effects on particle flow time. The analytical results are compared with the experimental data. It is shown that the very large variation of radiation gradient with shock−wave velocity is related to the strong dependency of shocked temperature with shock velocity within the range of 0.6−1.6 cm/μsec.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
