Because of the small size of typical atomic condensates, there is not a large length scale separation between the system size and the inter-vortex size, and therefore k-space is restricted. Numerical simulations suggest that turbulence is more likely to appear in the Vinen regime.<ref name=":5" /><ref name=":6" /><ref name=":8" /><ref>{{Cite journal|last1=Cidrim|first1=A.|last2=White|first2=A.
