Abstract
We have shown that maximal energies of the charged particles accelerated in the system of converging magnetohydrodynamic (MHD) flows can reach ≈ 1017 eV. The scheme of magnetic field amplification (MFA) applied to the previous non-linear model of particle acceleration in the colliding shocks allowed to make proper estimates for the value of turbulent magnetic field. The efficiency of the particle acceleration on the energy range larger than the "knee" in the cosmic rays spectrum (≈ 1014 – 1015 eV) makes the systems of colliding MHD flows important contributors to the overall high-energy cosmic rays population in the Galaxy.
