Abstract

We obtain two-dimensional exact analytic solutions for the structure of the hot accretionflows without wind. We assume that the only non-zero component of the stress tensor is Trϕ.Furthermore, we assume that the value of viscosity coefficient α varies with θ.We find radiallyself-similar solutions and compare them with the numerical and the analytical solutions alreadystudied in the literature. The no-wind solution obtained in this paper may be applied to thenuclei of some cool-core clusters.
