摘要： 针对数值模拟带微型涡流发生器(VG)的增升装置绕流过程中出现的典型问题,研究相应解决途径.引入面搭接网格技术,避免传统结构网格方法造成的网格数量过大问题;在微型涡流发生器网格上采用特殊边界条件处理以分别对应有/无涡流发生器的状态,排除网格变动对计算结果造成的干扰;研发出了面搭接网格生成技术与特殊边界处理方法结合的求解加装微型涡流发生器的增升装置流动数值模拟方法.研究结果表明:该方法在处理增升装置这类复杂外形、复杂流动问题以及加装涡流发生器的流动控制问题时,具有良好的数值计算精度,能够满足研究需要,为开展涡流发生器精细设计和参数优化的数值模拟研究提供了可靠的技术途径.

Abstract: To help carry out the numerical analysis of micro vortex generator (VG)used to control the flow separation of a high lift system, several crucial issues that occur during numerical simulation are solved in this paper. First, in order to avoid excessive grid number caused by the conventional point-to-point gird method, a patched grid technique is adopted. Second, a special boundary condition definition method is used to correspond respectively to the cases of the fitting and non-fitting of micro vortex generator, which will eliminate the disturbance caused by grid change. The combination of such two methods generates a new approach for the numerical analysis of a high lift system with micro vortex generator on it. The wind tunnel data prove that this approach achieves good numerical accuracy and can meet the needs of related research. It offers a reliable way during the numerical research of micro vortex generator design and parameter optimization.

Key words: high lift system, flow separation, flow control, micro vortex generator, numerical simulation, patched grid, turbulence model
