Turbulence in buoyancy-driven bubbly flows


The flow of suspension of deformable objects (bubbles or droplets) is omnipresent in a variety of natural and industrial processes. A swarm of rising bubbles in an otherwise quiescent fluid, at moderate volume-fraction, generates pseudo-turbulence studied by several experiments and numerical simulations over the last three decades. We present a Direct Numerical Simulation (DNS) study of buoyancy-driven bubbly flows. We investigate the statistical properties of the liquid velocity comparison and make comparisons with experiments. Using the scale-by-scale energy budget analysis, we study the role of surface tension and inertial forces.
