| Abstract(J) | 筒内で生じる不均一な自発点火は圧力波を成長させる要因であり，温度の空間勾配と自発点火遅れ時間の温度依存性に起因し，自発点火伝播速度が重要であると考えられている．本研究では，メタン価一定とし，燃料組成の違いが自発点火伝播速度に与える影響を調査した．また，自発点火遅れ時間を一定とし，自発点火遅れ時間の温度依存性の違いが自発点火伝播速度に与える影響を議論した． Translation |
| Abstract(E) | The effect of difference in fuel composition and pressure on the autoignitive propagation velocity was investigated by 0D and 1D numerical calculations with keeping the methane number consistent. When the ignition delay time was consistent, the effect of difference in temperature dependence of the ignition delay time on the autoignitive propagation velocity was discussed. Under high pressure conditions, there are intersection on the low temperature side of the Arrhenius plot. At that point, methane / ethane had a lower temperature dependence of ignition delay time, resulting in an increased in autoignitive propagation velocity. |
