论文摘要
我们研究了在低雷诺数下的微晶球仪的模拟中，调查了正规化stokeslets（MRS）方法的适用性。该研究所选的模型是众所周知的三个连接的球员游泳者。我们将结果与晶格Boltzmann方法，多颗粒碰撞动力学，Oseen张量方程的数值解和分析解决方案进行了比较，这些解决方案均取自Earl $ \ textit {et al。} $ [J。[J.化学物理。 126，064703（2007）]。对MRS进行了详细研究，我们的结果显示了与晶格Boltzmann方法以及与其有效性范围的分析解决方案的极好一致。我们得出的结论是，MRS非常适合这种模拟，提供了易于实施和代表复杂几何形状的优势。因此，它将自己作为更复杂的模拟的合适候选者。
We investigate the applicability of the Method of Regularized Stokeslets (MRS) in the simulation of micro-swimmers at low Reynolds number. The chosen model for the study is the well-known three linked spheres swimmer. We compare our results with the lattice Boltzmann method, multiparticle collision dynamics, a numerical solution of the Oseen tensor equation and an analytical solution, all taken from Earl $\textit{et al.}$ [J. Chem. Phys. 126, 064703 (2007)]. The MRS is studied in detail, and our results show an excellent agreement with the lattice Boltzmann method, and with the analytical solution in its range of validity. We conclude that the MRS is well suited for this type of simulation, offering advantages such as being easy to implement and to represent complex geometries. Therefore it presents itself as a suitable candidate for more complex simulations.
