Design of experimental apparatus for generation and measurement of an aerosol
… Two different cases, one with the low effective Atwood number and the other with higher effective Atwood number are investigated. In the case of low effective Atwood number the instability evolved is more like RMI rather than SDMI which is due to domination of Gas Atwood number over effect Atwood …

Oblique Shock Wave Effects on Impulsively Accelerated Heavy Gas Column
… air. The effects of density gradient (Atwood number, A), shock strength (Mach number, M), and column inclination angle (theta) were examined. Concentration was measured using Planar Laser Induced Fluorescence (PLIF) of an acetone vapor tracer mixed with the heavy gas jet and illuminated …

Fluids Viscosity Effect on Non-Isothermal Buoyancy-Driven Exchange Flow in Inclined Pipes
… flow is studied experimentally for different Atwood numbers, inclination angles and fluid pairs. The density difference drives the flow, that is achieved through added salinity for isothermal case and temperature difference for the non-isothermal case. Detailed benchmarking experiments were …

Covering Shock Wave Induced Interfacial Mixing: Numerical Study and a Control Primer
… Hexauoride immersed into unshocked air with Atwood number of 0.67. The perturbation is varied by setting different values for the wave amplitude and wave-number; the amplitude and wave-number effects on late-time mixing are studied separately and then such perturbation features are coupled …

Oblique shock interactions With perturbed density interfaces
… presented for both types of instability at Mach numbers 1.2, 1.67, and 2.0. Also, numerical parameter studies that vary the Atwood number, Mach number, and the droplet diameter are discussed. The cylindrical gas column represents a three-dimensional set of initial conditions which are often …

Effects of Compressibility and Variable-Density on the Instability Growth within Buoyancy-Driven Shear Layers
… Chung, et al. in the incompressible regime. The Atwood number A, and the isothermal Mach number Ma, are varied to investigate the effects of variable density and compressibility on the BSL, respectively. The results suggest that the flow exhibits two distinct flow regimes. An early time regime is …
