We are concerned with the time decay rates of strong solutions to a non-conservative compressible viscous two-phase fluid model in whole space R3. Compared previous related works, main novelty this paper lies fact that it provides general framework can be used extract optimal solution as well its all-order spatial derivatives from one-order highest-order, which same those heat equation. Further...

In this article, the two-phase water hammer theoretical and numerical simulation are provided. A mathematical formulation is presented to describe transient one-dimensional flow of bubbly gas-liquid mixtures without phase change in an horizontal pipe. The features two-fluid model for simulating flows investigated. governing equations were obtained from mass momentum conservation laws combined w...

in this study digital image correlation (dic) technique combined with a high speed video system was used to predict movement of particles in a water model. comparing with particle-image velocimetry (piv) technique, it provides a low cost alternative approach to visualize flow fields and was successfully employed to predict the movement of particles in a water model at different submergence dept...

a frequency-wavenumber-domain formulation is presented in this paper for calculation of the green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. the green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. the solution is in the frequency ...

Traditionally traffic flow models have been based on analogous physical phenomena. Though these models have been successful in representing traffic flow, there is a need to provide a systematic behavioural explanation for their existence. One such model is the two-fluid model which is analogous to the principles of Bose–Einstein condensation of particles at low temperatures. The model has been ...

We compute solitary wave solutions of a Hamiltonian model for large-amplitude long internal waves in a two-layer stratification. Computations are performed for values of the density and depth ratios close to oceanic conditions, and comparisons are made with solutions of both weakly and fully nonlinear models. It is shown that characteristic features of highly nonlinear solitary waves such as br...

A new model for cooling flows in X-ray clusters, capable of naturally explaining salient features observed, is proposed. The only requirement is that a significant relativistic component, in the form of cosmic rays (CR), be present in the intra-cluster medium and significantly frozen to the thermal gas. Such an addition qualitatively alters the conventional isobaric thermal instability criterio...
