| Abstract: | The numerical solution of pressure field of the submerged unfree jet flow is analyzed in detail. A corresponding mechanical model of the flow field and the second kind boundary condition are established. The rectangular net squares and the mark of boundary are given. Results show that accurate solutions of pressure could be obtained only from the pressure's Poisson equation and the points inside and close to the boundary could be solved according to different equations. |
