Comparative study of transition models for high-angle-of-attack behavior [PDF]
, 2019 This paper considers transition modeling for the flow over small unmanned aerial vehicles with a span of around 1 m. Such flows are characterized by very low values of turbulence intensity, and the main cause for transition corresponds to flow separation.

A Kinetic Alfven wave cascade subject to collisionless damping cannot reach electron scales in the solar wind at 1 AU [PDF]
, 2010 (Abridged) Turbulence in the solar wind is believed to generate an energy cascade that is supported primarily by Alfv\'en waves or Alfv\'enic fluctuations at MHD scales and by kinetic Alfv\'en waves (KAWs) at kinetic scales $k_\perp \rho_i\gtrsim 1 ...

Statistical features of rapidly rotating decaying turbulence: Enstrophy and energy spectra and coherent structures [PDF]
, 2018 In this paper we investigate the properties of rapidly rotating decaying turbulence using numerical simulations and phenomenological modelling. We find that as the turbulent flow evolves in time, the Rossby number decreases to $\sim 10^{-3}$, and the ...

Computational modeling of non-equilibrium condensing steam flows in low-pressure steam turbines
Results in Engineering, 2020 Condensation occurring in low pressure stages of steam turbines contributes to many losses in efficiency and damage to the stator blades such as corrosion and pitting. This problem has been observed profusely in power generation industries.
