In this paper we have shown the capability of the control variable method to compute various fluid problems. Until now 1-D or 2-D calculations was performed, but the method can easily generalized to 3-D flow problems. The implicitness of the method allows great time steps which is useful to obtain rapidly steady state flows. Further improvements have to be made in order to reduce numerical dissipation in order to obtain more precise solution.
