In this review a detailed study of the properties of elliptical and triangular eccentricities in the initial state of heavy ion collisions is presented. We use the model of random energy source distribution in the transverse plane within effective theory of color condensation. It is shown that the elliptical flow is closely related with the geometry of the ions collision. A triangular flow has a purely fluctuation nature and its dependence on centrality is determined exclusively overlap area.
