International Soil and Water Conservation Research, 2016 Hydrodynamic dispersion is a measure for describing the process of solute transport in porous media. Characterizing the dispersion of water flow within gravel is essential for the prediction of solute transport especially nonpoint source pollutants ...

Hydrodynamic characteristics of knotted and knotless purse seine netting panels as determined in a flume tank. [PDF]
PLoS ONE, 2018 Nylon (PA) netting is widely used in purse seines and other fishing gears due to its high strength and good sinking performance. However, hydrodynamic properties of nylon netting of different characteristics are poorly understood. This study investigated

Hydrodynamic Coefficients for Various Postures of the Underwater Manipulator [PDF]
Journal of Applied Fluid Mechanics, 2023 The hydrodynamic coefficients of underwater manipulators constantly change during their operation. In this study, the hydrodynamic coefficients of an underwater manipulator were calculated using the finite volume method to better explain its hydrodynamic

Computational prediction of hydrodynamic coefficients for heave motion [PDF]
Seatific Engineering Research Journal, 2021 In this study, the hydrodynamic coefficients associated with heave motion are obtained by using unsteady Reynolds-averaged Navier-Stokes (URANS) approach. The well-known Wigley hull is selected for the calculations of uncoupled added mass and damping coefficients (A33, B33) in deep water.

Do Hydrodynamic Dispersion Coefficients Exist? [PDF]
Physical Review Letters, 1996 Tracer dispersion is the simplest example of the flow of an inhomogeneous two-component mixture. We assume that the two components, the “tracer” and the “solvent,” have identical behavior but are distinguishable in the sense that they are assigned different “colors.” The model may be simple, but it is neither trivial nor irrelevant.

Surface charge and hydrodynamic coefficient measurements of Bacillus subtilis spore by optical tweezers. [PDF]
Colloids and Surfaces B: Biointerfaces, 2014 In this work we report on the simultaneous measurement of the hydrodynamic coefficient and the electric charge of single Bacillus subtilis spores. The latter has great importance in protein binding to spores and in the adhesion of spores onto surfaces ...

Kubo Formulas for Second-Order Hydrodynamic Coefficients [PDF]
Physical Review Letters, 2011 At second order in gradients, conformal relativistic hydrodynamics depends on the viscosity eta and on five additional "second-order" hydrodynamical coefficients tauPi, kappa, lambda1, lambda2, and lambda3. We derive Kubo relations for these coefficients, relating them to equilibrium, fully retarded 3-point correlation functions of the stress tensor ...
