A detailed three-dimensional computational model is developed to assess the potential of micron-scale field emission dielectric barrier discharge (FE-DBD) plasma actuators in non-premixed microburners with channel heights in the range of L z = 0.25–0.75 mm. Results for H 2 –O 2 combustion with Reynolds number Re = 100 are studied for different configurations of plasma actuator arrays. Without plasma actuation, results agree with corresponding experiments, although in this case the burner typically suffers from incomplete combustion due to thermal quenching, radical quenching, and slow diffusive mixing. For the range of conditions simulated, plasma actuation increases combustion completeness from 25%–70% to 40%–80% by enhancing mixing, generating radicals, and Joule heating. Ionic wind resulting from the FE-DBD plasma disrupts the otherwise simple laminar flow in the burner, accelerating the growth of a mixing layer and enhanci...

H 2 -O 2微燃烧的场发射等离子体增强

开发了详细的三维计算模型，以评估通道高度在L z = 0.25-0.75 mm范围内的非预混微型燃烧器中微米级场发射电介质阻挡放电（FE-DBD）等离子体致动器的潜力。对于等离子致动器阵列的不同配置，研究了雷诺数Re = 100的H 2 -O 2燃烧结果。没有等离子体致动，结果与相应的实验一致，尽管在这种情况下，燃烧器通常由于热淬火，自由基淬火和缓慢的扩散混合而遭受不完全燃烧的困扰。在模拟的条件范围内，等离子驱动通过增强混合，产生自由基和焦耳热，将燃烧完成度从25％–70％增加到40％–80％。
