  • 摘要:

    空腔流动尤其是高马赫数(Ma>2)空腔流动,存在强激波、强剪切和分离涡,及其相互之间的干扰,流动复杂,网格分布及网格生成的质量对模拟结果影响很大。将建立的基于非结构混合网格的自适应探测器,应用到高马赫数空腔流动数值模拟中,通过空腔标模算例考核,验证了采用网格自适应技术可以更好地模拟存在大分离和强剪切的高马赫数空腔流动。开展了马赫数、雷诺数等流动参数对空腔流动特性影响的研究,随马赫数增大空腔内动压急剧升高,自由流和剪切层对后壁面的冲击效应明显增强,压力分布的不均匀程度提高,后壁面上的压力峰值均逐渐增大。雷诺数增大会使后壁面处的压力峰值增大,并且高马赫数条件相比于低马赫数条件下雷诺数对腔内压力分布的影响更显著。
