Research Manager

The Flow Technology research group has a strong competence on multiphase flow modelling of industrial processes. The group has three market focuses, the Flow Assurance market, Multiphase reactors, and Generic Flow Modelling

Our three market focuses:

Flow Assurance market
To ensure safe and economical oil and gas processing and transport from the reservoir to point of sale efficient engineering tools are needed. This implies a continuous development and experimental validation of computer simulators for multiphase flow.

Expertise:

  • Modelling multiphase flow phenomenon – from micro to MACRO scale
  • The impact of surface chemistry
  • Hydrates, wax, asphaltenes, scale and sand
  • Separation
  • Thermodynamics

Multiphase reactors
To design, optimise and scale up multiphase reactors for energy/materials conversion with a strong emphasis on processes with integrated CO2 capture. The validated reactive multiphase modelling by dedicated experiments is used to develop novel reactor concepts and to accelerate the scale up of promising technologies.

Expertise:

  • Reactive multiphase flow modelling for the detailed simulation of fluidized and packed bed reactors
  • Development of 1D modelling tools for rapid simulation of fluidized and packed bed reactors
  • Development and scale up of Chemical Looping technologies
  • Multiscale modelling for reactor design and scale up
    • DEM-CFD modelling for catalyst design in packed bed reactors
    • CFD-Process flowsheet modelling for process design and optimisation
  • Dedicated lab scale experiments for
    • Demonstration of novel reactor concepts
    • Detailed multiphase model validation
  • Electrolysis processes
    • Magnetohydrodynamics
    • Population balance modelling (PBM)
    • PBM-Volume of fluid coupling
    • Bubble-bubble interaction phenomena

Generic Flow Modelling
To apply the competence on Computational Fluid Dynamics (CFD) to a variety of industrial applications to reduce risks and optimise operation.

Expertise:

  • Wind farm design
  • Atmospheric gas dispersion
  • Fouling

 

 

This animation shows the effect of internal obstructions on the degree of solids mixing inside a fluidized bed containing a sorbent for CO2 capture. Some degree of axial solids segregation is required to maximize CO2 capture efficiency. The case with no internals shows very good mixing and a uniform solids CO2 loading throughout the bed. Regularly spaced internals completely alter the bed behaviour, but mixing is still sufficient to result in a uniform solids CO2 loading. Only when internals are tightly grouped together, can a large degree of axial segregation be observed in the solids CO2 loading, resulting in better CO2 capture performance.
