Abstract

We study the effects of winds on advection dominated accretion flows in the presence of a global magnetic field under a self-similar treatment. The disk gas is assumed to be isothermal. For a steady state structure of such accretion flows a set of self similar solutions are presented. We consider the wind in a general magnetic field with three components (r,φ,z) in advection-dominated accretion flows. The mass-accretion rate \(\dot{M}\) decreases with radius r as \(\dot{M}\propto r^{s+1/2}\) , where s is an arbitrary constant. We will see, by increasing the wind parameter s, radial and rotational velocities increase.
