MPS法によるマイクロディスペンサーのシミュレーション(流体工学,流体機械)  [in Japanese] Numerical Simulation of a Micro-dispenser Using the MPS Method(Fluids Engineering)  [in Japanese]

The MPS method is a particle method which approximates motion of continua by discrete dynamics of a finite number of particles. Thus it is relatively easy to simulate complicated phenomena in multiphase flows or fluid-structure interaction. In this study, a micro-dispenser reported in Lindemann et al. (2004) is simulated using the MPS method. This microfluidic device offers a challenging problem of fluid-structure interaction and multiphase flows, where deformation of the elastic tube interacts with fluid flow and droplets are ejected changing the topology of the surfaces. The results are compared with the experiment to investigate applicability of the MPS method to microfluidic devices.
