Effects of Fuel-Side dilution and Pressure on Structure and Extinction Scalar Dissipation Rate of Syngas Nonpremixed Flames

질소희석과 압력이 석탄가스 비예혼합 화염구조와 소염 스칼라 소산율에 미치는 영향 해석

The present study has numerically investigated the effects of fuel-side dilution and pressure on flame structure and extinction scalar dissipation rate of turbulent syngas nonpremixedd flames. Numerical results indicate that for highly diluted case, peak temperature is decreased and stoichiometric mixture fraction is increased. By decreasing the pressure and the nitrgen dilution levelcreased, the extinction scalar dissipation rate is increased.
