粒子通过惯性微流控装置迁移到聚焦流线。提出了一种用奇异点表示粒子在任意截面惯性微流控通道中迁移速度的数值计算方法。给出了对渐近分析的改进,改进了奇异近似的正则性,使流场和压力场的有限元近似更加有效。实验结果表明,该方法计算效率高,能够捕捉到由于通道形状和雷诺数变化而引起的粒子聚焦位置的分岔。
Particles traveling through inertial microfluidic devices migrate to focusing streamlines. We present a numerical method that calculates migration velocities of particles in inertial microfluidic channels of arbitrary cross section by representing particles by singularities. Refinements to asymptotic analysis are given that improve the regularity of the singularity approximation, making finite element approximations of flow and pressure fields more effective. Sample results demonstrate that the method is computationally efficient and able to capture bifurcations in particle focusing positions due to changes in channel shape and Reynolds number.
