On energetics and inertial-range scaling laws of two-dimensional magnetohydrodynamic turbulence
, 2012 L. Blackbourn was supported by an EPSRC post-graduate studentship.We study two-dimensional magnetohydrodynamic turbulence, with an emphasis on its energetics and inertial range scaling laws.

Numerical Study of the Effect of Freestream Turbulence on by-pass Transition in a Boundary Layer [PDF]
, 2014 We use direct numerical simulations in the presence of free-stream turbulence having different values of intensity, T u, and integral length scale, L, in order to determine which kind of structures are involved in the path to transition of a boundary ...

Generalized atmospheric turbulence MTF for wave propagating through non-Kolmogorov turbulence
Optics Express, 2010 A generalized exponential spectrum model is derived, which considers finite turbulence inner and outer scales and has a general spectral power law value between the range 3 to 5 instead of standard power law value 11/3. Based on this generalized spectrum model, a new generalized long exposure turbulence modulation transfer function (MTF) is obtained ...

Mixing Behavior of Natural Gas and Hydrogen in a High‐Efficiency Vane (HEV) Static Mixer
Energy Science &Engineering, EarlyView.Static mixers play a crucial role in the safe transport of hydrogen‐blended natural gas. Computational fluid dynamics (CFD) was employed to investigate the effects of structural parameters of the HEV static mixer on the mixing behavior and homogeneity of natural gas and hydrogen. The modeling approach was well validated against experimental data.

When Does Top Management Team Diversity Matter in Large Organizations?
Journal of Organizational Behavior, EarlyView.ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

, 2012 We argue that the hypothesis of preservation of shape of dimensionless second- and third-order correlations during decay of incompressible homogeneous magnetohydrodynamic (MHD) turbulence requires, in general, at least two independent similarity length ...

Scintillation index of optical plane wave propagating through non Kolmogorov moderate-strong turbulence [PDF]
, 2007 An optical plane wave propagating through atmospheric turbulence is affected by irradiance fluctuations known as scintillation. The scintillation index of an optical wave in strong turbulence can be analyzed by extended Rytov theory, which uses filter ...

Lagrangian Time Scale of Passive Rotation for Mesoscale Particles in Turbulence
Frontiers in Marine Science, 2020 Turbulence induces rotation in the living and the non-living materials in the ocean. The time scale of rotation for a living organism is important in understanding an organism's feeding efficiency, mating, prey capture rate, etc.

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...
