The effect of liquid compressibility on the dynamics of a single, spherical cavitating bubble is studied. While it is known that compressibility damps the amplitude of bubble rebounds, the extent to which this effect is accurately captured by weakly compressible versions of the Rayleigh-Plesset equation is unclear. To clarify this issue, partial differential equations governing conservation of ...

The crush behaviors of steel tubes filled with nanoporous-materials-functionalized liquids are experimentally investigated under quasi-static and dynamic conditions. Results show that the nanoporous-materials-functionalized liquid can enhance the load-carrying and the energy absorption capacities of thin-walled tubes, as the buckling mode is affected. The effective buckling stress increases wit...

Hydrodynamic interactions between particles confined in a liquid-filled linear channel are known to be screened beyond a distance comparable to the channel width. Using a simple analytical theory and lattice Boltzmann simulations, we show that the hydrodynamic screening is qualitatively modified when the time-dependent response and finite compressibility of the host liquid are taken into accoun...

The theory of the acoustics of dilute bubbly liquids is reviewed, and the dispersion relation is modified by including the effect of liquid compressibility on the natural frequency of the bubbles. The modified theory is shown to more accurately predict the trend in measured attenuation of ultrasonic waves. The model limitations associated with such high-frequency waves are discussed.

The effect of granular pressure on the fluctuation volume fraction is investigated experimentally in a gas–solid flow system. Granular compressibility, defined by response fractions pressure, also measured. It found that there exists critical beyond which transition from coexistence liquid-like phase and gas-like to homogenous fluids takes place. heterogenous characterized an abrupt change comp...

in this study for the first time a new description of compressibility factor is rendered based on the virial expansion. the compressibility factor as a function of m-factor is qualitatively and quantitatively expressed. at first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. the results show, when the com...

The concentration dependency of the isothermal compressibility of the Na-Cs liquid alloy at T=373K is calculated by the variational method with hard-sphere reference system. The local Animalu-Heine model pseudopotential and Toigo-Woodruff exchange-correlation function are used for the calculation. Very good agreement with experimental data is achieved.
