Momentum-scalar coupled turbulence with anomalous momentum and scalar diffusions. Part 2: With short-range external force and implementation in electrokinetic turbulence
Wei Zhao
We extend the generalized anomalous diffusion framework established in Part I to the short-range forcing regime (), where the multiscale-force dominated (MFD) subrange is i…

Momentum-scalar coupled turbulence with anomalous momentum and scalar diffusions. Part 1: Without external force and with long-range external force
Wei Zhao
We present a theoretical model for momentum--scalar coupled turbulence in which both fields undergo anomalous diffusion, described by fractional biharmonic operators of orders $γ/4…
