Two-Dimensional Slow Viscous Flow Due to a Stokeslet Near a Slit

Slit 近傍의 Stokeslet 에 의한 2次元의 느린 粘性流動


Abstract

Two-dimensional slow viscous flow due to a stokeslet near a slit is investigated on the basis of Stokes approximation. Velocity fields and stream function are obtained in closed forms by finding two sectionally holomorphic functions which are determined by reducing the problem to Riemann-Hilbert problems. The force exerted on a small cylinder is calculated for the arbitrary position of the cylinder translating in an arbitrary direction. The features of fluid flow are also investigated.
