A Self-similar Solution of Hot Accretion Flow: The Role of the Kinematic Viscosity Coefficient

We investigate the dependency of inflow-wind structure a hot accretion flow on kinematic viscosity coefficient. In this regard, we propose model for coefficient to mimic behavior magnetorotational instability that would be maximal at rotation axis. Then, compare our with two other prescriptions from numerical simulations flow. solve two-dimensional hydrodynamic equations flows in presence thermal conduction. The self-similar approach is also adopted radial direction. calculate properties inflow and wind such as velocity, density, angular momentum three models prescription. On inspection, find suggested less efficient extracting outward where solutions are applied than it models. obtained paper might applicable hydrodynamical flows.
