Turbulent dynamics in an ultracold Bose gas, in one, two and three spatial dimensions, is analysed by means of statistical simulations using the classical field equation. A special focus is set on the time-evolution of characteristic quantities such as the energy and velocity distributions, vortical density and spectral function. The results give insight into the dynamics of an ultracold Bose gas in the quantum turbulent regime.
