TL;DR: In this paper, the volume-averaged form of the linear momentum conservation equations for two-phase flow is examined to clarify momentum interaction effects between phases, and the interphase force model is applied to predict experiments on void propagation in bubbly flows.

TL;DR: In this article, the authors measured the flooding limits in countercurrent air-water flow through pipe elbows consisting of an upper vertical leg and a lower leg which is horizontal or slightly inclined, and found that flooding is caused by unstable wave formation (slugging) at the hydraulic jump which forms in the lower pipe limb close to the bend.

TL;DR: Using functional analysis principles, a numerical method was developed for solving this inverse problem in this article, where the method was applied for reconstructing the density distribution of a two-phase flow, and it was shown that the method can be used to solve the inverse problem of density reconstruction.
Abstract: Radiation scattering imaging (or density reconstruction) is viewed as an inverse problem. Using functional analysis principles, a numerical method is developed for solving this inverse problem. The method is applied for reconstructing the density distribution of a two-phase flow.

TL;DR: In this paper, the rotational and irrotational flows are first calculated and then reconstituted into the time-dependent velocity field through the use of Hodge's decomposition theorem.
Abstract: Numerical methods for the solution of free interface problems are reviewed. For two-dimensional problems, an application of the random vortex method is proposed in which the rotational and irrotational flows are first calculated and then reconstituted into the time-dependent velocity field through the use of Hodge's decomposition theorem. The irrotational part is calculated by conformally mapping the flow, bounded to one side by the interface, into a strip at every step, followed by use of the Gram-Schmidt orthonormalization process to solve Laplace's equation for the velocity potential. An alternative for the irrotational flow calculation, in which the free interface is represented by a vortex sheet and the boundary integral method is applied, is also discussed. The rotational field is calculated by generating vortex sheets to satisfy the no-slip boundary conditions, and by following the convective and diffusive motion of the sheets and vortex blobs. The technique is shown to yield accurate results for damping of solitary waves on shallow liquids.
