Scientific paper

A fully three-dimensional solar wind model that incorporates momentum and heat addition from Alfvén waves is developed. The proposed model upgrades the previous one [Usmanov, 1993a,b], by considering self-consistently the total system consisting of Alfvén waves propagating outward from the Sun and the mean polytropic solar wind flow. The simulation region extends from the coronal base (1 Rsolar) out to beyond 1 AU. The fully 3-D MHD equations written in spherical coordinates are solved in the frame of reference corotating with the Sun. At the inner boundary, the photospheric magnetic field observations are taken as boundary condition and wave energy density is prescribed to be proportional to the magnetic field strength. An example of the model application is presented.
