Abstract: With the choices of dependant variables and cell face velocity, the convergency speed and computational accuracy of SIMPLE algorithm employed in the computation of complex flows are analyzed. The mistakes of basic concepts found in literature are corrected, and a method whose good effects in improving the algorithm showed by numerical tests, is put forward.

Key words: SIMPLE algorithm, convergency characteristics, dependant variable, cell-face velocity
