Gasoline anti-knock quality, defined by the research and motor octane numbers (RON and MON), is important for increasing spark ignition (SI) engine efficiency. Gasoline knock resistance can be increased using a number of blending components. For over

Light naphtha is a fully blended, low-octane (RON = 64.5, MON = 63.5), highly paraffinic (> 90% paraffinic content) fuel, and is one of the first distillates obtained during the crude oil refining process. Light naphtha is an attractive low-cost fuel

In this study, measurements were performed to assess the overall mixing in jet-stirred reactors (JSRs) passively agitated by feed nozzles. The reactor diameter, nozzle shape, and nozzle diameter were varied to determine the effects of these geometric

Sensors based on absorption spectroscopy rely on accurate simulations to obtain quantitative data. The simulations, in turn, depend on accurate line lists. To test the quality of the ExoMol line list, a comparison of a simulation based on the line li
