Three-dimensional multiphase flow and flow with phase change are simulated using a simplified method of tracking and reconstructing the phase interface. The new level contour reconstruction technique presented here enables front tracking methods to naturally, automatically, and robustly model the merging and breakup of interfaces in three-dimensional flows. The method is designed so that the ph...

nowadays, with the advent of new satellite services, the need for resource management in the emerging fifth generation satellite systems (5g-satellite) is inevitable. thus, to solve this problem, the bandwidth manager for resource reservation in satellite link is mandatory. on the other hand, due to limited resources, their resource management­ is essential. in order to resource management in 5...

Multi phase and multi component flows are ubiquitous in nature as well as in many man-made processes. Multi-phase flows typically manifest a wide variety of geometrical patterns (or flow regimes) of associated phases depending on several system conditions. These patterns include, but are not limited to, bubbly, slug, churn or annular flows. In the case of boiling this may lead to Departure from...

The generally accepted phase diagrams for the discrete ZZN spin models in two dimensions imply the existence of certain renormalisation group flows, both between conformal field theories and into a massive phase. Integral equations are proposed to describe these flows, and some properties of their solutions are discussed. The infrared behaviour in massless and massive directions is analysed in ...

phase turbulence, but underpredict the two-phase fluctuation velocities, and the difference between the two model predictions is not obvious. 4. The nonlinear k-«-kp model has no problem of convergence encountered in the implicit algebraic stress model. 5. In two-dimensional flows with small geometrical sizes the NKP model can save about 50% computation time than the USM model. However, in thre...

We revisit Taylor dispersion in oscillatory flows at zero Reynolds number, giving an alternative method of calculating the Taylor dispersivity that is easier to use with computer algebra packages to obtain exact expressions. We consider the effect of out-of-phase oscillatory shear and Poiseuille flow, and show that the resulting Taylor dispersivity is independent of the phase difference. We als...
