Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...

The dynamical and thermal structure of an opaque boundary layer, connecting a classical T Tauri star (CTTS: M∗ = 1M , R∗ = 4.3R , Teff = 5000K) with its accretion disk (Ṁ = 10−7M /yr), has been computed, including particularly the effect of a turbulence-driven global heat transport. The inner boundary has been shifted deeper and deeper into the star’s envelope in order to determine how this aff...

Sea ice is in almost constant motion in response to wind, ocean currents, and forces transmitted within the ice cover itself, thus there is nearly always a zone of sheared Sow between the ice and underlying, undisturbed ocean where turbulence transports momentum, heat, salt, and other contaminants vertically. The zone in which these turbulent Suxes occur, which can span from a few to hundreds o...

Abstract The presence of waves is proven to be ubiquitous within nocturnal stable boundary layers over complex terrain, where turbulence in a continuous, although weak, state activity. typical approach based on Reynolds decomposition unable disaggregate from contributions, thus hiding any information about the production/destruction energy injected/subtracted by wave motion. We adopt triple-dec...
