The process of explosion venting to air in a cylindrical vented vessel, filled with stoichiometric methane-air pre-mixed gas, was simulated using the co-located grid SIMPLE scheme based on k-ε turbulence model and 'Eddy Dissipation' combustion model. 采用基于k-ε湍流模型和漩涡破碎燃烧模型的同位网格SIMPLE算法,对充满当量比的甲烷-空气预混气的柱形泄爆容器,向空气中泄爆的过程进行了数值模拟。
It is necessary that the cathode should provide sufficient plate current, which is also a basic condition for the reduction of the grid dissipation power. 阴极需提供充裕电流,这是栅耗得以降低的基础条件。
