Shock–turbulence interactions at high turbulence intensities

Journal of Fluid Mechanics, 2019
Shock–turbulence interactions are investigated using well-resolved direct numerical simulations (DNS) and analysis at a range of Reynolds, mean and turbulent Mach numbers ($R_{\unicode[STIX]{x1D706}}$, $M$ and $M_{t}$, respectively). The simulations are shock and turbulence resolving with $R_{\unicode[STIX]{x1D706}}$ up to 65, $M_{t}$ up to 0.54 and $M$

Intensity of microcarrier collisions in turbulent flow

Bioprocess Engineering, 1994
A model is developed, allowing estimation of the share of inelastic interparticle collisions in total energy dissipation for stirred suspensions. The model is restricted to equal-sized, rigid, spherical particles of the same density as the surrounding Newtonian fluid. A number of simplifying assumptions had to be made in developing the model. According

The role of turbulence in internal phosphorus release: Turbulence intensity matters

Environmental Pollution, 2019
Hydrodynamic fluctuations can trigger sediment suspension concomitantly with internal phosphorus release, while the interactive effect of turbulence mixing and sediment suspension on the regulation of phosphorus dynamics is in need of deep understanding.

Turbulent flow effects on NMR imaging: Measurement of turbulent intensity

Medical Physics, 1991
A general expression has been derived for the NMR signal from a fluid in steady but turbulent flow in a magnetic field gradient. The precise dependences of the spin echo amplitude on both flow and experimental parameters are described in terms of the temporal autocorrelation function for velocity fluctuations in the fluid.

Widespread Intense Turbulent Mixing in the Southern Ocean

Science, 2004
Observations of internal wave velocity fluctuations show that enhanced turbulent mixing over rough topography in the Southern Ocean is remarkably intense and widespread. Mixing rates exceeding background values by a factor of 10 to 1000 are common above complex bathymetry over a distance of 2000 to 3000 kilometers at depths greater than 500 to 1000 ...
