Abstract: Numerical solutions for the integral curves of the velocity fieldstreamlines, the density contours, and the accretion rate of a steady-stateflow of an ideal fluid with $p=K n^\gamma$ equation of state are presented. Thestreamlines and velocity fields associated with a black hole and a rigid spherein a Reissner-Nordstr\-om-anti de Sitter spacetimes are studied in somedetail. For each case the fluid density is studied using contour lines. For$\gamma eq 2$, we found that the studied properties of the fluid are moresensitive to variations of the electric charge and the cosmological constant.Also, the accretion rate was found to increase or decrease when thecosmological constant increases or decreases respectively.
