Particularly gas-liquid flows play an important role in the field of power plant technology, pipeline design, multi-phase reaction engineering and separation processes such as distillation or extraction units.
The flow morphology, the degree of dispersion and the phase fraction are important input parameters for the design of downstream process equipment. In contrast to two-phase flow in vertical and horizontal two-phase flow the influence of complex pipe modifications on the flow is not well described.
Numerical methods are usually used to obtain detailed 3D information on the characteristics of the flow parameters, while simultaneously being flexible towards geometries and operational conditions.

This work aims on implementing gas-liquid two-phase flow in elbow bends using CFX.

Tasks:

  • Literature analysis on two-phase CFD modelling in pipes
  • Implementation of a gas-liquid two-phase flow in elbow bend using CFX
  • Flow simulation and characterization of the two-phase flow up- and downstream of the bend; comparison with available experimental data
