This work describes an experimental investigation about the coalescence of pairs of gas slugs rising in vertical columns of liquids covering a wide range of liquid viscosities. The experiments were performed in columns with 19, 32 and 52 mm of internal diameter and slug coalescence was followed by m

โฆ Synopsis
A formulation and solution of the problem of steady seepage in a vertical column when the liquid enters from below are given. The boundary conditions on the free surface are linearized by the transposition method. Expressions are obtained for the dispersion surface and the components of the seepage rate and pressure. A numerical analysis of the solution is carried out.

Patterns formation of gravitactic microorganism in a vertical cylinder is described by the Navier-Stokes equation coupled with the microorganism conservation equation. The control volume method is used to solve numerically these equations. It is found that when the Peclet number is decreased, the cr
An experimental study is presented about the interaction between two slugs rising through a co-current flowing liquid in vertical tubes with 22, 32 and 52 mm internal diameters. For the conditions studied the liquid flow pattern in the wake of the slugs was turbulent and the main liquid flow regime
