The Relationship

The two-phase flow field of SX type static mixer is analyzed in this paper. The comprehensive influencing factors are considered during analyzing the relationship of two-phase flowage parameters in practical device. Then the theoretical study is carried out. The two-phase flow is impinged, separated, flowed around and merged. The mixture effect is strengthened. The analytic calculation is carried out according to the practicable turbulent flow pattern and the results is useful for the structure parameters effectively selection and the characteristic optimization.

The Cross

A new SVLX static mixer is original designed by the author with the structure of alternative connection of the SV static mixing unit and cross shaped stationary helical fin. The two-phase flow is sheared, separated, impinged and rotated by SV static mixing unit, as well as whirled by the cross shaped stationary helical fin. Hence the mixer efficiency is enhanced. The most advantage of this design is the mixer efficiency is more enhanced with none applied force. Followed by the static mixer structure illustration, the preliminary analysis of the two-phase flow field is carried out, which provides some proofs for the selection and optimization of the new SVLX static mixer structural parameters.

The Relationship

Vibration in mechanical devices is one of the major problems in engineering field including power generated industry. In this study we focused on the method and possible equipment design availability in reduction of vibration level. A brief overview of the outcomings of pipeline vibrations is presented, the sources of vibrations are listed and possible solutions for eliminating vibrations are described. Devices for passive quenching of pressure pulsations in pipelines with a two-phase flow are considered. We presented the description of the experimental stand on the investigation of the influence of a two-phase flow on the vibration of sections of a pipeline under different flow patterns of a coolant, as well as the procedure for conducting an experiment to study the properties of developed and manufactured swirl models. An animated model was developed that reflects the relationship of swirl geometry with the reduction of the vibro-displacement of the pipeline as a result of passive action on a two-phase flow.

Riser Pipe

Four different riser pipe exit configurations were modelled and the flow across them analysed using STAR CCM+ CFD codes. The analysis was limited to exit configurations because of the length to diameter ratio of riser pipes and the limitations of CFD codes available. Two phase flow analysis of the flow through each of the exit configurations was attempted. The various parameters required for detailed study of the flow were computed. The maximum velocity within the pipe in a two phase flow were determined to 3.42 m/s for an 8 (eight) inch riser pipe. After thorough analysis of the two phase flow regime in each of the individual exit configurations, the third and the fourth exit configurations were seen to have flow properties that ensures easy flow within the production system as well as ensure lower computational cost. Convergence (Iterations), total pressure, static pressure, velocity and pressure drop were used as criteria matrix for selecting ideal riser exit geometry, and the third exit geometry was adjudged the ideal exit geometry of all the geometries. The flow in the third riser exit configuration was modelled as a two phase flow. From the results of the two phase flow analysis, it was concluded that the third riser configuration be used in industrial applications to ensure free flow of crude oil and gas from the oil well during oil production.

Entrance Angle

Calculation fluid dynamics software Fluent was used to conduct three-dimensional numerical simulation on gas-liquid two-phase flow field in a wet flue gas desulfurization scrubber. The k-ε model and SIMPLE computing were adopted in the analysis. The numerical simulation results show that the different gas entrance angles lead to internal changes of gas-liquid two-phase flow field, which provides references for reasonable parameter design of entrance angle in the scrubber.
