| Abstract(J) | 近年の圧縮着火機関ではCN燃料の適用により，更なる環境負荷への低減が期待されている．一方，CN燃料は従来の軽油と表面張力など物性値が異なる可能性があり，混合気の形成に寄与する空気導入特性の変化が予想される．そこで本研究では蛍光PIVを用いて噴霧への空気導入特性に及ぼす燃料物性の影響を調査した． Translation |
| Abstract(E) | The application of carbon-neutral (CN) fuels to compression-ignition engines has been expected to further reduce environmental impact. There is possibility that physical properties of CN fuels such as surface tension are different from those of conventional diesel fuel, and it is expected that characteristics of air entrainment induced by a spray are changed due to differences in the physical properties. Therefore, the surroundings gas flow of the spray near the nozzle exit was evaluated using a fluorescent PIV technique, and the effect of fuel physical properties on the air entrainment in a spray was investigated. |
