Simulation on accretion disks in binary dwarfs is often modeled using the alpha prescription. It usually treats the dynamic viscosity coefficient as a constant term. This implies that with a local dependent alpha coefficient, it would obtain superficial density instabilites that could increase the accreted mass toward the compact star. This work uses a parametrization on the viscosity coefficient in the alpha prescription, assuming a dependence with the local disk temperature, using a two dimensional SPH code. Works in the literature has shown tha this instablities might be the cause of the flare state on this kind of binaries.
