AB - Unsteady settling behavior of solid spherical particles falling in water as a  Newtonian fluid is investigated in this research. Least square method (LSM),  Galerkin method (GM), LSM - Padé and numerical model are applied to analyze  the characteristics of the particles motion. The influence of physical  parameters on terminal velocity is discussed and it is showed that LSM and GM  are efficient techniques for solving the governing equation. Among these  methods, LSM- Padé demonstrates the best agreement with numerical results.  The novelty of this work is to introduce new analytical methods for solving  the nonlinear equation of sedimentation applicable in many industrial and  chemical applications.
