Liquid Flow Simulation onto the Horizontal Square Rod Array

Flow Pattern Identification and Pressure Drop Calculation for Gas-Liquid Flow in a Horizontal Pipeline

Two phase gas-liquid flow pattern in a horizontal pipeline is predicted very accurately using a newly-developed analytical relation. The pattern identification is based on one of the most widely used graphs, the Baker diagram, modified in a way that compensates for the unrealistic oversimplifications of recent works. The Kern's method of pressure drop calculation is used to obtain the frict...

Large Eddy Simulation of the Gas-Liquid Flow in a Square Cross-sectioned Bubble Column

Column N.G. Deen, T. Solberg and B.H. Hjertager Chem. Eng. Lab., Aalborg Univ. Esbjerg; Niels Bohrs Vej 8; DK-6700 Esbjerg; Denmark Abstract In this work the use of large eddy simulations (LES) in numerical simulations of the gas-liquid flow in bubble columns is studied. The Euler-Euler approach is used to describe the equations of motion of the two-phase flow. It is found that, when the drag, ...

Numerical Simulation of the Incompressible Laminar Flow Over a Square Cylinder

Simulation of fluid flow over a square cylinder can be performed in order to understand the physics of the flow over bluff bodies. In the current study, incompressible laminar flow over a confined square cylinder, with variable blockage factor has been simulated numerically, using computational fluid dynamics (CFD). The focus has been on vortex-induced vibration (VIV) of the cylinder. Vorticity...

Numerical Simulation of Flow inside the Square Cavity

Numerical simulations have been undertaken for the benchmark problem in a Square cavity by using computational fluid dynamics software. This work aims at discussing the fundamental numerical and computational fluid dynamic aspects which can lead to the definition of the following meshing methods and turbulence models. The meshes used for the simulation are hexahedral, hexahedral cell with near ...
