| Abstract: | By directly coupling the contra-velocities and pressure , ,, p instead of u, v, w, p in a controlled volume in body-fitted coordinates, an adaptive Block Implicit Finite Volume Method (BLIFV) is presented. The drawback of the original BLIFVin solution of incompressible flows within complex geometry boundariesin a staggered grid system is completely eliminated. Good performance is obtained in computing the flow in a 90 。bend. And the calculated results are found in good agreement with the experime... |
