3 years ago - The present study addresses the influence of a DC electric field on the laminar burning velocity (SL) of premixed flat methane/air flames. （直流電界の予混合平面メタン空気火炎層流燃焼速度への影響を調べた）
- All measurements were performed using the heat flux method. （すべての計測は熱流束法を用いて行われた）
- The effect measured was the (limited) increase of laminar burning velocity induced by the electric field which can reach values up to ∼8% from SL0 for a stoichiometric mixture.（電界による量論混合気において層流燃焼速度の上昇は８％にとどまった）
- An exponential relation between the applied voltage and the change in the adiabatic burning velocity ΔSL=SL,U−SL,U=0 was found. （印加電圧と断熱燃焼速度の変化には指数関数的な関係を持つことが明らかになった）
- The linear relation between the change in adiabatic burning velocity and the imposed electric current or power allows considering responsible mechanisms via a thermal power release and/or direct influence on the global chemical reaction rate.（断熱燃焼速度と電流および電力の線形な関係から，熱的な電力の放出がグローバルな化学反応速度に影響を及ぼすことが主なメカニズムであることを示唆している）

Experiments have been carried out on a flat flame stabilized between condenser electrode configurations with varying inter-electrode distance that affects the electric field strength. The grounded burner plate served as a lower electrode. The upper electrode was a non-cooled platinum wire screen woven in a stainless steel ring. All measurements were performed using the heat flux method. The effect measured was the (limited) increase of laminar burning velocity induced by the electric field which can reach values up to ∼8% from SL0 for a stoichiometric mixture. An exponential relation between the applied voltage and the change in the adiabatic burning velocity ΔSL=SL,U−SL,U=0 was found. The linear relation between the change in adiabatic burning velocity and the imposed electric current or power allows considering responsible mechanisms via a thermal power release and/or direct influence on the global chemical reaction rate. Numerical simulations, to study the possible role of conversion of electric energy into thermal energy and the effect of the electric field on the chemical reactions were conducted. The dominant role of the chemical reaction path was demonstrated. The results indicate that the electrode configuration is applicable to influence the laminar burning velocities, requiring a relative low power input.} }
