Differential diffusion in low Reynolds number water jets
Experimental data on differential diffusion between two species with large and quite disparate Schmidt numbers were obtained in a turbulent water jet by optically measuring the two species concentrations simultaneously. Experimental conditions were chosen so that the species were dilute and did not affect the water density thereby avoiding inertial effects. Differential diffusion was found to b...
متن کاملStructure and dynamics of low Reynolds number turbulent pipe flow.
Using large-scale numerical calculations, we explore the proper orthogonal decomposition of low Reynolds number turbulent pipe flow, using both the translational invariant (Fourier) method and the method of snapshots. Each method has benefits and drawbacks, making the 'best' choice dependent on the purpose of the analysis. Owing to its construction, the Fourier method includes all the flow fiel...
متن کاملSurface-sampled simulations of turbulent flow at high Reynolds number
Funding information European Commission Horizon 2020, Grant/Award Number: 671571; Engineering and Physical Sciences Research Council (EPSRC), Grant/Award Number: EP/L000261/1 Summary A new approach to turbulence simulation, based on a combination of large eddy simulation (LES) for the whole flow and an array of non–space-filling quasi-direct numerical simulations (QDNS), which sample the respon...
متن کاملInteractions within the turbulent boundary layer at high Reynolds number
Simultaneous streamwise velocity measurements across the vertical direction obtained in the atmospheric surface layer (Reτ 5 × 10) under near thermally neutral conditions are used to outline and quantify interactions between the scales of turbulence, from the very-large-scale motions to the dissipative scales. Results from conditioned spectra, joint probability density functions and conditional...
متن کاملLow-Reynolds-number swimming at pycnoclines.
Microorganisms play pivotal functions in the trophic dynamics and biogeochemistry of aquatic ecosystems. Their concentrations and activities often peak at localized hotspots, an important example of which are pycnoclines, where water density increases sharply with depth due to gradients in temperature or salinity. At pycnoclines organisms are exposed to different environmental conditions compar...
