A Numerical Simulation for the Propulsion of Axisymmetric Micro-Hydro-Machine by Contractive and Dilative Motion
수축팽창 운동에 의한 축대칭 마이크로-하이드로-머신의 추진을 위한 수치 시뮬레이션
Abstract
A Numerical simulation for the propulsion of axisymmetric body by contractive and dilative motion is carried out. The present analysis shows that a propulsive force can be obtained in highly viscous fluid by a contractive and dilative motion of axisymmetric body. An axisymmetric analysis code is developed with unstructured grid system for the simulation of complicated motion and geometry. The developed code is validated by comparing with the results of stokes approximation with the problem of uniform flow past a sphere in low Reynolds number(
