A Simplified Solution for Advection Dominated Accretion Flows with Outow

The existence of out ow in the advection dominated accretion ows has been con rmed by both numerical simulations and observations. the out ow models for adaf have been investigated by several groups with a simple self similar solution. but this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the ow; so, it is necessary to obtain a global solution for adafs with out ow. in this paper, we use a simpli ed global solution to study the structure of adaf in the presence of out ow. in this method which is proposed by yuan et al (2008, hereafter ymn08), the radial momentum equation is replaced by a simple algebraic relation between angular velocity and keplerian angular velocity to avoid the difficulty of the calculation of global solution. we consider the radial dependence for mass accretion rate m = m out(r=rout)^s where s is a constant and we do not change the other dynamical equations. we investigate the variation of physical quantity of accretion ow which is caused by out ow. the results that we obtained comply with our expectations from the in uence of out ow on the structure of accretion ow.
