Abstract:
The material documented in this thesis represents a contribution to the knowledge of the sponsoring company relating to assessment of the effects of two-phase flow on corrosion. Techniques available in the open literature for determining hydrodynamic characteristics of two-phase flow such as flow regimes and wall shear stresses were reviewed and compared with particular emphasis on stratified and slug flow regimes. The research work conducted improves the sponsoring company's knowledge and understanding of these areas providing a platform for undertaking two-phase flow related projects and developing / extending this business function. The work presented also enhances the company's qualitative understanding of momentum and mass transfer under two-phase flow providing a focus for driving future developments in laboratory based corrosion assessment. Initial work was undertaken to compare and validate hydrodynamic models studied using data available in the open literature a limited amount of which was from high pressure large diameter systems. This enhances confidence in models implemented and indicates the performance and accuracy expected. A feature of the work conducted of primary importance to the sponsoring company was generation of the first stages of a knowledge base supporting company projects whilst conforming to company QA procedures. In depth study of fundamental two-phase hydrodynamic models conducted during this research also provides a platform for future investment in commercially available technology. The material presented in this thesis enables investment in such technology with the benefit of detailed knowledge of models commonly used and critical understanding of expected performance and suitability.
