Significance of secondary baroclinic hydrodynamic instability on mixing enhancement in shock-bubble interaction
Different strength of hydrodynamic instability can be induced by the variations in the initial diffusion of shock bubble interaction (SBI), while the influence of hydrodynamic instability on variable-density mixing in SBI remains unclear. The present study aims to investigate the hydrodynamic instability of SBI through high-resolution numerical simulations. To isolate each factor within this instability, a circulation control method is employed to ensure consistent Reynolds number Re and Peclec…

Scale-by-scale energy transfers in bubbly flows
Variable density buoyancy-driven bubbly flows allow for multiple definitions of scale-dependent (or filtered) energy. A priori, it is not obvious which of these provide the most physically apt scale-by-scale budget. In the present study, we compare two such definitions, based on (a) filtered momentum and filtered velocity (Pandey et al., 2020), and (b) Favre filtered energy (Aluie 2013, Pandey et al., 2023). We also derive a Kármán-Howarth-Monin (KHM) relation using the momentum-velocity corr…
