Computational Simulation of Hydrodynamic Convection in Rising Bubble Under Microgravity Condition
In this work, rising of a single bubble in a quiescent liquid under microgravity condition was simulated. The related unsteady incompressible full Navier-Stokes equations were solved using a conventional finite difference method with a structured staggered grid. The interface was tracked explicitly by connected marker points via hybrid front capturing and tracking method. One field approximatio...
متن کاملNumerical Investigation of the Effect of Bubble-Bubble Interaction on the Power of Propagated Pressure Waves
The study of bubble dynamics, especially the interaction of bubbles, has drawn considerable attention due to its various applications in engineering and science. Meanwhile, the study of the oscillation effect of a bubble on the emitted pressure wave of another bubble in an acoustic field which has less been investigated. This issue is investigated in the present study using the coupling of Kell...
متن کاملNumerical simulation of single bubble rising in vertical and inclined square channel using lattice Boltzmann method
A lattice Boltzmann equation (LBE)model based on the Cahn–Hilliard diffuse interface approach is used to investigate thedynamics of a bubble rising in a vertical and inclined square channelwith large density and viscosity ratios. Deformation parameter D, film thickness d, and terminal velocity Ut of the bubble are interrelated quantities which depend on non-dimensional numbers such as Bond numb...
متن کاملObservation of Stacking Fault Tetrahedral in TWIP Steel
Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.
متن کاملMeasurement of pressure and density inside a single sonoluminescing bubble.
The average pressure inside a sonoluminescing bubble in sulfuric acid has been determined by two independent techniques: (1) plasma diagnostics applied to Ar atom emission lines, and (2) light scattering measurements of bubble radius vs time. For dimly luminescing bubbles, both methods yield intracavity pressures approximately 1500 bar. Upon stronger acoustic driving of the bubble, the sonolumi...
