| Abstract: | According to the particle motion equations given by Maxey and Riley, an analytical solution of the degenerative equation of a sphericai solid particle in very small relative motion Reynolds number is obtained, and the particle following behaviours, which depend on the external force, initial condition and the properties of the flow fileds, are discussed. The effects of the different frequencies and density rates on the flow following behaviours in homogeneous turbulent flow are also analysed. |
