The analytical solution of the problem for four models: Happel’s, Kuwabara’s, Kvashin’s and Cunningham’s (usually referred to as Mehta-Morse’s) is derived. The drag force acting on each particle in the cell is evaluated for the four models. In limiting cases the drag force reduces to earlier analytical results. Results are discussed and presented in graphical forms.https://www.jafmonline.net/article_1442_0c8f84c726167f787f45fe0ddb3f0446.pdf
