Abstract: The problem of Stokes entry flow into a semi-infinite circular cylindrical tube was studied in this paper. A new kind of series solutions was derived. Their evident difference from the solutions in References [1,2] is that the present solutions don ’t involve infinite integral. So they are favourable for calculation. We calculated an example by allocated method and obtained satisfied results.
