摘要 对圆柱绕流的电磁控制进行了实验和数值研究.实验在转动水槽中进行,通过吊杆将装有电磁激活板的圆柱插在槽内液体中.吊杆上的应变片用于测试圆柱的阻力,注入适当的染料用来显示流场.数值模拟时,流场的基本方程为指数极坐标中考虑场力的Navier-Stokes方程,计算采用ADI格式和FFT格式.结果表明,实验与计算所描述的流场具有相同的变化趋势.在开环控制时,即Lorentz力为常数时,旋涡脱体可被有效抑制,涡街消除,阻力减少.另外,基于上述Navier-Stokes方程,推导了优化控制所需的伴随方程,并利用同样的数值方法对此进行数值求解.根据伴随优化理论得到实时变化的优化控制参数,对优化控制过程中的流场变化进行了讨论.
