Web14 apr. 2024 · The model is based on the Raether-Meeks criteria and estimates the breakdown probability at a spatial location as a function of the electric field, gas pressure and the total Townsend ionization coefficient at the point. 2D parametric studies are performed for different spark gaps and aspect ratios to assess the dependence of … Web9 apr. 2014 · We develop a criterion for spark-breakdown in non-uniform field geometries with positive polarity and small electrode separations so that breakdown evolves without the formation of a leader. We arrive at the spark-breakdown criterion by framing it in terms of gain and instability conditions, whose relative importance is established from an …

WebMeek criterion As mentioned above, the formation of the streamer depends directly on the charge of the electron avalanche’s head part. That is, when the space charge increases and the electric field distortion is strengthened to a certain extent, enough photoionization will occur in space which leads to the formation of the streamer. dj px10WebThe meek criterion is also shown in orange as well, with the separation between the two being constant at higher pressures The data clearly follows a separate slope at higher … dj pyWebRaether-Meek criterion for prediction of electrodeless discharge inception on a dielectric surface in different gases. / Chvyreva, A.; Pancheshnyi, S.; Christen, T. et al.
