摘要
等离子体流动控制是一种新概念的主动流动控制技术,已成为国际上空气动力学和气动热力学领域新兴的研究热点。分析了等离子体气动激励建模仿真的特点和国内外的研究现状,研究了目前常用的4种等离子体气动激励的建模仿真方法,对各种仿真方法的优缺点进行了归纳。分析了等离子体气动激励建模仿真研究的发展趋势,即今后更多的研究工作将偏向粒子模拟方法,建模时考虑的因素会越来越多,从非定常的角度对等离子体气动激励展开研究,使得模型与实际物理过程更加接近;更高来流速度下的等离子体流动控制的仿真研究将增多,和实际应用的条件更为接近。深入的仿真研究有助于揭示等离子体气动激励及其和边界层相互作用的物理本质,以促进等离子体流动控制技术在我国的研究和发展。
Plasma flow control, as a novel active flow control technique, has become a newly - rising focus in the international aerodynamics and aerothermodynamics fields. The character and research status quo of plasma aerodynamic actuation modeling are introduced in the paper. A detail specification of four basic models of plasma aerodynamic actuation is discussed. The simulation technologies, the merits and defects of the methods are discussed. The development direction of plasma flow control is analyzed. More researches based on particle simulation will be developed in the future. More and more factors, such as the unsteady characteristic of plasma aerodynamic actuation, will be considered in modeling, which makes the simulation model much more accord with the physical process. Researches of higher inflow velocity will be carried on to meet the application demand. The deep simulation research is a help to revealing the physical essence of plasma aerodynamic actuation and its interplay with boundary layer, so as to promote the research and development of plasma flow control technology in our country.
