A Lagrangian fluctuation-dissipation relation for scalar turbulence
An exact relation is derived between scalar dissipation due to molecular diffusivity and the randomness of stochastic Lagrangian particle trajectories. This result equates the dissipation of scalar fluctuations to the variance of the scalar inputs due to initial scalar values, scalar sources, and boundary fluxes as those are sampled backward in time by the stochastic trajectories. The relations...
متن کاملenergy dissipation over large-scale roughness for both transition and uniform flow conditions
rock chutes are natural river training structures and are efficient energy dissipaters too. from the hydraulic and environmental point of view, rock chutes have become important structures in the natural river morphology. a physical study was conducted and flow properties were measured over rough bed materials of a rock chute, which was assembled at the pitlab center of the university of pisa, ...
متن کاملDissipation-Scale Turbulence in the Solar Wind
We present a cascade model for turbulence in weakly collisional plasmas that follows the nonlinear cascade of energy from the large scales of driving in the MHD regime to the small scales of the kinetic Alfvén wave regime where the turbulence is dissipated by kinetic processes. Steady-state solutions of the model for the slow solar wind yield three conclusions: (1) beyond the observed break in ...
متن کاملEnergy dissipation and fluctuation response for particles in fluids.
An equality was recently proved relating energy dissipation to the difference of the response and velocity correlation functions for a class of Langevin equations. We generalize this for the physically important case of particles in a fluid, where bath fluctuations are nonlocal in time due to hydrodynamic modes. We also show that the inclusion of a mass term does not alter the result and provid...
متن کاملImprint of large-scale flows on turbulence.
We investigate the locality of interactions in hydrodynamic turbulence using data from a direct numerical simulation on a grid of 1024(3) points; the flow is forced with the Taylor-Green vortex. An inertial range for the energy is obtained in which the flux is constant and the spectrum follows an approximate Kolmogorov law. Nonlinear triadic interactions are dominated by their nonlocal componen...
