Based on the numerical solution non-stationary Ginzburg-Landau equations, we investigated the evolution of the order parameter of superconducting channels with different lengths under applied voltage (so-called voltage-driven regime). We calculated current-voltage characteristics for channels of different lengths and found out the origin of theirs characteristic disorder oscillations. For very long channels in the certain voltage interval we reveal the chaotic dynamic of the order parameter. Collected data allowed us to plot the most complete and detailed phase diagram of the resistive state of the superconducting channel in the voltage-driven regime.
