论文摘要
在本文中，我们提出了具有时间依赖的电场的电动力流的数值模型，并带有气泡的传输。此类模型应用于电子喷射打印，例如添加剂制造（AM）和对流冷却，静电沉淀，等离子体辅助燃烧。 我们提出了一个由两个模型组成的耦合模型。第一个模型是基于汉堡方程的潜在流体动力学模拟模型。第二个模型是基于级别方程的传输模型，该模型在流场中运输气泡。我们得出了两个耦合建模方程的建模，并讨论了解决此类问题的脱钩和耦合版本。在数值分析中，我们讨论了基于拆分方法和级别技术的求解器方法。在第一个数值结果中，我们提出了液体流量中气泡的脱钩和耦合模型模拟。
In this paper we present numerical models for electrodynamical flows with time-dependent electrical fields with transport of bubbles. Such models are applied in e-jet printing, e.g., additive manufacturing (AM), and convective cooling, electrostatic precipitation, plasma assisted combustion. We present a coupled model, consisting of two models. The first model is the underlying hydrodynamical simulation model, which is based on the Burgers' equation. The second model is a transport model based on level-set equations, which transport the bubbles in the flow field. We derive the modeling of the two coupled modeling equations and discuss decoupled and coupled versions for solving such delicate problems. In the numerical analysis, we discuss the solvers methods, which are based on splitting approaches and level-set techniques. In the first numerical results, we present decoupled and coupled model simulations of the bubbles in the liquid flow.
