The project is about the computational study of Single Expansion Ramp Nozzle (SERN). A comparison is carried out for four different cowls of length 2h with initial arc radii of 0mm, 10mm, 20mm and 30mm. The ramp and the cowl are angled. The study elaborates the effect of arc (0mm, 10mm, 20mm and 30mm) in the cowl on the performance of the SERN. The CFD procedure is validated by comparing with experimental results. The optimum design is obtained by analyzing the computational result.
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.
