Abstract:High-enthalpy gas streams in a real engine or wind tunnel will contain some trace gases; however, this is often ignored in many studies. To investigate transverse fuel-jet mixing and combustion characteristics in a high-enthalpy inflow with trace-gas species, large-eddy simulations based on the HyShot II configuration have been adopted and verified. It was found that a trace amount of atomic oxygen (O) and nitrous oxide has a direct significance on ignition delay times and can, therefore, influence the overall… Show more
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.
