According to the light curves obtained from observations of LMXB (Low-Mass X-ray Binary), within the framework of the Shakura-Sunyaev model it was found that the alpha viscosity parameter, which characterizes the mass transport in the accretion disk, lies in the range of 0.2-1. But simulations of the magnetorotational instability give values an order of magnitude smaller (about 0.03). In this work, we considered an additional source of matter transfer, namely, wind. We simulated the disk with the influence of the wind, which can decrease value of alpha parameter. As the result we receive the dependence of the change in the alpha on wind parameters. And if the decrease in alpha parameter is strong enough we conclude that the presence of wind can strongly affect the viscosity value, as well as the entire evolution of the disk as a whole.
