Experimental study on the effect of arm slope on turbulent structure of weir-flume combination
Shui kexue jinzhan, 2023 The weir-flume combination facility is advantageous for flow monitoring in mountainous areas.The sediment distribution behind the weir and the downstream erosion can be affected by arm slope owing to the changes in the hydrodynamic characteristics of the

Interpreting Eddy Fluxes [PDF]
Journal of Physical Oceanography, 2007 Abstract A generalization of the transformed Eulerian and temporal residual means is presented. The new formulation uses rotational fluxes of buoyancy, and the full hierarchy of statistical density moments, to reduce the cross-isopycnal eddy flux to the physically relevant component associated with the averaged water mass properties. The

An Intestine-Derived Neuropeptide Controls Avoidance Behavior in Caenorhabditis elegans
Cell Reports, 2017 Adjusting to a continuously changing environment is a key feature of life. For metazoans, environmental changes include alterations in the gut microbiota, which can affect both memory and behavior.

Optimal Nonlinear Eddy Viscosity in Galerkin Models of Turbulent Flows
, 2015 We propose a variational approach to identification of an optimal nonlinear eddy viscosity as a subscale turbulence representation for POD models. The ansatz for the eddy viscosity is given in terms of an arbitrary function of the resolved fluctuation ...

Algorithms and Models for Turbulence Not at Statistical Equilibrium
, 2015 Standard eddy viscosity models, while robust, cannot represent backscatter and have severe difficulties with complex turbulence not at statistical equilibrium. This report gives a new derivation of eddy viscosity models from an equation for the evolution
