Resumen
Numerical solutions for the integral curves of the velocity field (streamlines), the density contours and the accretion rate of a steady-state flow of an ideal fluid with p = Kn(gamma) equation of state orbiting in a core-dipole-shell system are presented. For gamma not equal 2, we found that the nonlinear contribution appearing in the partial differential equation for the velocity potential has little effect in the form of the streamlines and density contour lines, but can be noticed in the density values. The study of several cases indicates that this appears to be the general situation. The accretion rate was found to increase when the constant gamma decreases. 19 15 4085 4093
