Atomic layer etching (ALE) is gaining prospects in industry application,as the precision demands for smaller feature patterning is more urgent.The ALE process uses cyclic passivation and etching steps to achieve monolayer precision etching.Ion bombardment energy plays an important role,as the matching of energy and ALE window can influence the precision,selectivity damage and profile control,Tailored voltage waveform[1]is proposed as a flexible ion energy modulation method,it can give near mono-energy ions,or even the customized IEDs,according to the demands for etching control.

高阶精度格式常用于时-空多尺度的复杂流动,如LES、DNS和CAA等。但是,在复杂网格中的工程应用方面,高阶格式的应用广度还不及2阶格式。为了采用高阶有限差分格式模拟复杂外形的复杂绕流,我们以WCNS格式核心,讨论了无粘通量的影响,采用了粘性项交错差分方法、网格导数守恒算法、多块对接网格技术、多块拼接网格技术等。通过对高超空心圆柱-裙、尖(钝)双锥、捆绑火箭模型等数值模拟表明高阶格式在高超声速激波
无人机在舰船上起降过程要比在地面上困难得多。除了受到复杂海况的影响外,还会受到绕过舰船产生的舰面气流扰动。在无人机近舰飞行过程中,舰船流场会对无人机的飞行轨迹和姿态产生不利的影响,严重威胁飞行和着舰的安全。舰船流场会对无人机飞行动力学建模产生重要的影响,需建立其流场分布模型,此外,为了提高导引和控制系统的准确性和鲁棒性,需要对无人机近舰飞行过程中的气动力特性进行研究分析,为无人机的安全着舰提供参考
本文在课题组内部编写的雷诺平均N-S方程求解器的基础上添加了层流-湍流转捩预测方法,从而预测由Tollmien-Schlichting (T-S)波不稳定性导致的转捩.T-S波不稳定性导致的自然转捩可以由简化eN方法预测,可以使用Drela和Giles准则或者Arnal-Habiballah-Delcourt准则.
以Busemann消波原理为基础,采用二维NS方程数值模拟方法,研究亚跨超声速、零攻角状态下双层翼翼型厚度、相对位置对阻力特性的影响规律。在此基础上,分析攻角不为零度状态下的流场特征,通过调节双层翼配置方式,降低了阻力,获取了较好的升阻特性。基于二维情况研究结果,分析了三维流动情况下的双层翼阻力特性,并考虑翼身干扰、翼面后掠等因素的影响规律,获取了亚、跨、超声速状态下具备较好升阻特性的双层翼布局形
迎风格式被广泛的应用于计算空气动力学中的对流通量计算。抑制和消除Carbuncle等激波不稳定现象是迎风格式研究中的一个传统课题;同时,湍流、摩阻和热流等问题的计算要求迎风格式具有良好的粘性分辨率。计算实践发现,AUSM+与K-CUSP-X等在结构化网格中能够稳定捕捉激波的迎风格式在非结构三角形网格中出现了明显的激波不稳定现象。通过给定网格形式,进一步说明了网格对激波稳定性的影响。为了研究迎风格式
