Note on the Propagation of Disturbances in a Liquid Containing Gas Bubbles
ثبت نشده
چکیده
In a liquid containing gas bubbles the speed of sound is less tham that in each phase separately. Using the equations of motion for a hõmogeneous liquid containing gas bubbles it is shown that the dominating attenuation of an infinitesimal disturbance is that due to the second viscosity. In the propagation of a finite compressive disturbance an expression for the time required for the disturbance to displaty shock characteristics is found in terms of the initial disturbanee profile and the liquid-gas ratio.

A method for detecting bubbles in two-phase gas-liquid flow
Detecting bubble in two-phase flow has been a basic issue in two-phase flow systems. A new method for measuring the frequency of bubble formation is presented in this paper. For this purpose, an electronic device was designed and constructed which works based on a change in intensity of laser beam. For this purpose, continues light beam is embedded just above the needle, which is received by a ...
متن کاملVoid Fraction Disturbances in Bubbly
-The paper is concerned with the flow of dispersions of gas bubbles in liquid, with bubble sizes such that the inertia forces on the bubbles are of importance to the dynamics. One-dimensional conservation equations are derived, which govern the flow when the deviations from the uniform state are small. These are used to describe the features of the propagation of void fraction disturbances, and...
متن کاملShock Propagation in Polydisperse Bubbly Liquids
We investigate the shock dynamics of liquid flows containing small gas bubbles, based on a continuum bubbly flow model. Particular attention is devoted to the effects on shock dynamics of distributed bubble sizes and gas-phase nonlinearity. Ensemble-averaged conservation laws for polydisperse bubbly flows, together with a Rayleigh–Plesset-type model for single bubble dynamics, form the starting...
متن کاملLiquid Temperature Effect on Sound Propagation in Polymeric Solution with Gas Bubbles
Acoustic properties of polymeric liquids are high sensitive to free gas traces in the form of fine bubbles. Their presence is typical for such liquids because of chemical reactions, small wettability of solid boundaries, trapping of air in technological operations, etc. Liquid temperature influences essentially its rheological properties, which may have an impact on the bubble pulsations and so...
