To clarify the mechanism of gas plugging caused by gas–liquid separation in a helical axial multiphase flow pump under two-phase conditions, pattern, bubble distribution, and evolution were studied high-speed camera technology. It is found that phase presents four different forms with inlet volume fractions: isolated flow, linear airbag emulsion flow. The increase fraction promotes aggregation bubbles changes pattern inside impeller. This change can be alleviated increasing rotational speed...
SUMMARY The penalty finite element method for Navier–Stokes equations with nonlinear slip boundary conditions is investigated in this paper. Since class of include the subdifferential property, weak variational formulation a inequality problem second kind. Using approximation, we obtain optimal error estimates between exact solution and approximation solution. Finally, show numerical results which are full agreement theoretical results.

We studied the dependence of thermodynamic variables in a sonoluminescing (SL) bubble on various physical factors, which include viscosity, thermal conductivity, surface tension, equation state gas inside bubble, as well compressibility surrounding liquid. The numerical solutions show that existence shock waves SL parameter regime is very sensitive to these factors. Furthermore, we even without waves, reflection continuous compressional at center can produce high temperature and picosecond...
By solving numerically the full set of hydrodynamic equations governing pulsation a bubble, we show that shock waves are often absent in stable sonoluminescing bubble. Nevertheless, for wide range physical parameters, continuous compressional wave emerges and heats up resulting black-body radiations have pulse heights widths agree with experimental data. Shock waves, being much less robust, not essential single-bubble sonoluminescence.
The spherical Couette flow between two concentric spheres with only the inner sphere rotating is simulated by solving 3D incompressible Navier-Stokes equations a fifth order upwind compact finite difference method. Two moderate clearance ratios, β = (R2 − R1)/R1 0.14 and 0.18, respectively, are chosen for comparison previous experimental numerical results. First, spiral Taylor-Görtler (TG) vortex at Re 1110 [W.

We numerically study the wide-gap spherical Couette flow between two concentric spheres with inner sphere rotating and outer one stationary. Two clearance ratios, 0.50, are chosen to investigate transition scenarios of spiral instabilities increasing Reynolds number (). For , we first obtain steady 1-vortex at by using for a medium gap as initial condition. The exists it collapses back basic when . then detect gradually. becomes unstable where waves wavenumber m = 6 appear first. Increasing...
To simulate bubble dynamic behaviors under an electric field conveniently and accurately, a volume-of-fluid, level set, smoothed physical parameter (VOF+LS+SPP) method based on FLUENT is first proposed. Compared with the VOF VOF+LS methods FLUENT, VOF+LS+SPP has very high precision maximum deviation only 7%. In addition, its simulation results are superior to those obtained by front tracking, LS phase in literature almost same data acquired VOSET method. Finally, proposed used investigate...
