A second generation URANS approach for application to aerodynamic design and optimization in the automotive industry
… at a practicable computational cost. For the flow past a car, unsteady turbulent flow structures are generated in the separation off the windshield, the mirrors, the wheels, and in the wake of the car body.

Experimental study of fish response to turbulent flow fields generated by in-stream structures
… when considering the impact of in-stream structures like dams or fish passages during stream restoration projects. Research is needed in both laboratory and field environments to better understand how fish respond to different hydrodynamic conditions resulting from various aquatic …

Turbulent interactions between stream flow and near-subsurface flow: a laboratory approach using particle image velocimetry and refractive index matching
Turbulent flow over a rough, porous gravel bed (particle diameter, D = 1.27 cm) is investigated in the laboratory using particle image velocimetry (PIV) and refractive index matching (RIM). This combination allows for detailed examination of flow fields both in the near-bed region and within the …

Fish swimming optimization and exploiting multi-body hydrodynamic interactions for underwater navigation
… Underwater, vision is usually limited, but flow structures resulting from the hydrodynamic interactions between inert and/or living bodies contain rich information, which fish can read through a dedicated sensory system, the lateral line. Fish can even extract energy from these flow …

Active heat transfer enhancement in integrated fan heat sinks
… sinks typically use a separate fan to force air flow over heated fins, the new design incorporates centrifugal fans directly into the body of a loop heat pipe with multiple planar condensers. These "integrated fans" rotate between the planar condensers, in close proximity to the hot surfaces, …

Modelling turbulence and transport of buoyant material in the ocean surface mixed layer
… turbulence and mixing of oceanic waters. These turbulent flows govern the distribution of buoyant materials including oil droplets and microplastics, which have significant implications for marine life and safety. However, turbulent flow structures are often too small to be resolved by global or …

3-D Numerical Modeling of Turbidity Currents
… experiments are limited to small-scale flows, are time- consuming and are not necessarily easier when it comes to measuring flow properties or establishing relationships between the turbulent flow structures and the transport and deposition of sediment. Numerical modeling of turbidity …

Sturcture of Three-Dimensional Separated Flow on Symmetric Bumps
Surface mean pressures, oil flow visualization, and 3-velocity-component laser-Doppler velocimeter measurements are presented for a turbulent boundary layer of momentum thickness Reynolds number, 7300 and thickness delta over two circular based axisymmetric bumps of height H = delta and 2delta and …
