RISNumerical Approach to Study Nonuniform Gas–Liquid Distribution in the Refrigerant Distributor in an Air Conditioner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Factors that influence the nonuniform gas–liquid distribution in refrigerant distributors in air conditioners were studied. Gas–liquid flows in twopass and multipass distributors were numerically simulated with a ...
Late Fuel Simulation Near Nozzle Outlet of Fuel Injector During Closing Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Late fuel during closing of the valve of a fuel injector and fuel films stuck on the wall around the nozzle outlets are sources of particulate matters (PM). In this study, we focused on the effects of the valve motions on ...
Effects of Opening and Closing Fuel-Injector Valve on Air/Fuel Mixture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lower engine emissions like CO2, particulate matter (PM), and NOx have recently become more necessary in automobile engines to protect the earth's environment. Keeping uniformity of air/fuel mixture and decreasing fuel ...
Simulation of Coarse Droplet and Liquid Column Formed around Nozzle Outlets Due to Valve Wobble of a Gasoline Direct Injection Injector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The generation of particulate matter (PM) is one problem with gasoline direct-injection engines. PM is generated in high-density regions of fuel. Uniform air/fuel mixtures and short fuel-spray durations with multiple ...
