In a very general manner, "renormalization" deals with the evolution of the description … WebOct 5, 2024 · Using a quantum field theory renormalization group, we consider models of advection of a vector field and a tracer field by a compressible turbulent flow. Both advected fields are considered passive, i.e., they do not have a backward influence on the fluid dynamics. The velocity field is generated by the stochastic Navier-Stokes equation. WebRenormalization group theories, coherent structures, and the Lagrangian and Eulerian frameworks for turbulent diffusion are then discussed, as well as coherent structures, non-Newtonian fluid turbulence, and the numerical simulation of turbulence.

WebMar 5, 2024 · First, the kinetic energy of each particle is now nonzero; its mass-energy increases from m to mγ. But in addition, the volume occupied by the cloud has been reduced by 1 / γ due to length contraction. We’ve picked up two factors of gamma, so the result is ρ → ργ2. This is different from the transformation behavior of a vector.
