We have solved steady-state, axisymmetric viscous two-dimensional (2D) fluid equations of motion
for accretion and outflows in spherical polar coordinates (r, θ, φ). First time in the analytical study,
we have used two azimuthal components of the viscous stress tensors namely, τrφ and τθφ. We
investigated the 2D disk structures around a black hole by integrating along r- and θ- directions. We
found supersonic and subsonic regions in the inflow region and the outflows occurred in the
subsonic inflow region above the equatorial plane. We also found that the structure and size of the
2D disk are affected by the viscosity of the flow and the ADAF size of the disk. We also explored
the outflows, no outflows, and failed outflows solutions around the BH.
