Computational Techniques for Multiphase Flows

Combined or multiphase flows of solid/liquid or solid/gas are in most cases present in many commercial fields, and their habit is complicated and hard to foretell in lots of instances. using computational fluid dynamics (CFD) has emerged as a robust software for the certainty of fluid mechanics in multiphase reactors, that are ordinary within the chemical, petroleum, mining, nutrients, beverage and pharmaceutical industries.

Hydraulic Engineering III

Hydraulic study is constructing past the borders of conventional civil engineering to fulfill expanding calls for in normal dangers, structural defense overview and in addition environmental learn. Hydraulic Engineering III comprises sixty two technical papers from the third Technical convention on Hydraulic Engineering (CHE 2014, Hong Kong, 13-14 December 2014), together with the 2014 Structural and Civil Engineering Workshop (SCEW 2014) and the 4th Workshop on atmosphere and defense Engineering (WESE 2014).

0, along the radial and tangential directions, respectively. 0. 0, respectively. 18. The streamline, which runs from point (1,0) to point (2,1), is shown in the Figure, superimposed on the prescribed velocity vector field. The velocity vectors vary in direction and magnitude, which is a good test to the extent of the accuracy of the NIMO numerical scheme in conditions where false diffusion is not uncommon. Equations (20), (25), (26), and (27) are applicable to 2D cylindricalpolar coordinates flows.

10. 5 for Pe = 1 for 59 × 59grids and θ = 45 degrees. 4, arises from the initial guess. The exact analytical solution of the test problem is used as the initial guess for φ, φx , φy , and φxy for all runs reported in the present work. 5. In this case, φ is equally transported by convection and by diffusion. 11. 5)] versus Peclet number for 59 × 59 square grids and θ = 45 degrees. 10 shows that the hybrid scheme produced skewed profiles of φ along the y-axis, while NIMO properly predicts symmetrical profiles.
