This contribution investigates the effects of duty cycle and mass flow of synthetic air and oxygen on the efficiency of ozone generation in multi-hollow surface dielectric barrier discharge (MSDBD). It discloses that the efficiency of ozone generation in MSDBD is significantly higher compared with standard coplanar DBD, surface DBD and volume DBDs. Ozone production yield reached 205.5 ± 29.1 g (kW h) −1 (40% duty cycle, 8 slm) and 413.91 ± 58.7 g (kW h) −1 (100% duty cycle, 8 slm) at an energy cost of 8.7 and 4.3 eV/molecule for synthetic air and oxygen, respectively. Such high ozone yields arose out of the intrinsic characteristics of MSDBD ceramics, which were efficiently cooled by the flow of the working gas. The amplitude modulation of low-frequency 5 kHz high-voltage sine waveforms facilitates controlled O 3 production at a nearly constant rate of yield. Since the correct evaluation of ozone production yield requires precise determination of th...

多空心表面介质阻挡放电：具有灵活性能和最高效率的臭氧发生器

该研究调查了多空表面介电势垒放电（MSDBD）中合成空气和氧气的占空比，质量流量对臭氧生成效率的影响。它公开了与标准共面DBD，表面DBD和体积DBD相比，MSDBD中产生臭氧的效率明显更高。臭氧产量为205.5±29.1 g（kW h）-1（40％占空比，8 slm）和413.91±58.7 g（kW h）-1（100％占空比，8 slm），能源成本为8.7和合成空气和氧气分别为4.3 eV /分子。MSDBD陶瓷的固有特性产生了如此高的臭氧产量，MSDBD陶瓷通过工作气体的流动有效地冷却了。低频5 kHz高压正弦波形的幅度调制有助于以几乎恒定的产率来控制O 3的产生。由于对臭氧产量的正确评估需要精确确定臭氧的产生量。
