| Abstract: | This paper puts forth a numerical method to deal with the basic electrically-charged gas-solid flow around a cylinder, that is, getting steady solutions by iterative method,discretizing governing equations by finite-difference mthod, and dealing with the solid-phase discontinuity by artificial viscosity. The computational results prove that the numerical method can deal with strong solidphase discontinuity. Furthermore, the method can also be applied to the numerical computation of the two-phase flow of a suspension involving a strong discontinuity. |
