Fluid turbulence is commonly associated with stronger drag, greater heat transfer, and more
efficient mixing than in laminar flows. In many natural and industrial settings, turbulent liquid …

Bubbly flows involve bubbles randomly distributed within a liquid. At large Reynolds
number, they experience an agitation that can combine shear-induced turbulence (SIT) …

The injection of gas bubbles into a turbulent boundary layer of a liquid phase has multiple
different impacts on the original flow structure. Frictional drag reduction is a phenomenon …

Hydrodynamic flows exhibit turbulent behaviour which is not well understood till date. When
a fluid is in a gravitational field, the flow becomes even more complex due to the gravity …

High-speed imaging is in popular demand for a broad range of experiments in fluids. It
allows for a detailed visualization of the event under study by acquiring a series of image …

An experimental investigation of the flow generated by a homogeneous population of
bubbles rising in water is reported for three different bubble diameters (d= 1.6, 2.1 and 2.5 …

Budgets of the turbulent kinetic energy from direct numerical simulations (DNSs) of disperse
bubbly channel flows are used to develop a model for bubble-induced turbulence in the …

Three-dimensional particle tracking velocimetry (PTV) and phase-sensitive constant
temperature anemometry in pseudo-turbulence–ie flow solely driven by rising bubbles–were …

In turbulent free-surface flows, the deformation of the surface leads to air bubble entrainment
and droplet projections when the turbulent shear stress is greater than the surface tension …

A quantitative description of the interaction between the turbulence eddies and bubble
groups is crucial for the prediction of the bubble size distribution in bubble columns when …
