Abstract:The operating point where the compressor speed lines, and the engine’s operating line meet is critical. Thus, improvement of the efficiency at that point is of paramount importance. Through systematic development of the single-stage supercharger by (i) incremental improvements to the compressor impeller, (ii) the arrangement and development of the diffuser vanes, and (iii) the shape of the outer volute/spiral, significant gains in the performance of the single-stage compressor have been made.
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.
