Abstract
© 2016 ICIC International. Electro-osmotic flow through a cylindrical tube is investigated numerically based on the finite difference method with the successive over relaxation (SOR) method using the Fortran language. The effect of the pressure weight parameter β and the tolerance τ of the SOR method on the SOR convergent rate and the maximum error of the continuity equation are examined. The results show that a low-value of β and a highvalue of τ give a good convergent rate of the SOR method. Moreover, the value of the external electric field plays an important role on the convergent rate of the SOR method but it has no impact on the maximum error of the continuity equation.
