This work deals with the detailed physics and numerical solution of a two-component solar wind model, consisting of small-scale Alfven waves and convected structures. In particular, we present numerical results which qualitatively reflect many of the observed features of the radial and spectral evolution of the turbulent energies, the residual energy, the cross-helicity and Alfven-ratio in high-speed solar wind streams. These features are the following: the formation of a characteristic inclined eye, which evolves between the energy spectra displayed over the frequency axis and tends to close in the radial development of the spectra, a steepening of all spectra towards Komogorov-like F-5/3 spectra, the development of the normalized cross-helicity towards a constant not much less than one and the formation of a trough form of the Alfven ratio with a z-shaped left boundary. By weighting special terms in the equation differently, we can also cast light on the physical role of parametric conversion model terms, wave-structure scattering model terms, nonlinear terms, spherical expansion terms and their effects on the radial evolution of turbulent energies in high-speed solar wind streams.
