摘要：

This note examines the stability of a stationary velocity solution of the Tchen's equation, describing the motion of a spherical particle with a Reynolds number much less than unity in a uniform unsteady fluid flow. The results show that the stationary solution is unstable if the ratio of the particle and fluid densities rho(p)/rho(f)< 7/4. Therefore, applying the stationary solution is not justified in this case. (C) 2000 American Institute of Physics. [S1070-6631(00)00307-X].
