Fig. 4: Velocity scalings of active turbulence.
From: Mitigating density fluctuations in particle-based active nematic simulations
a The velocity contribution due to active flows, \({v}_{{{{{{{\rm{av}}}}}}}}-{v}_{{{{{{{\rm{av}}}}}}}}^{0}\), for all four formulations of cellular activity. The dashed line indicates the theoretically expected scaling of vav ~ α1/2. b The velocity length scale of active turbulence ℓv in the turbulence regime. The dotted line indicates the theoretically expected scaling of ℓv ~ α−1/2. ("Part.'', Eq. (6), blue; “Cell'', Eq. (8), red; “Mod. Part.'', Eq. (12), cyan; “Mod. Cell'', Eq. (11), yellow).
