Large Eddy Simulation Of Multiphase Pipe Flow Using Experimental Inflow Data

Coventry University - Centre for Flow Measurement and Fluid Mechanics

THE PROJECT

Multiphase gas/liquid flows pipes are important in the power industry (boiler tubes) and the hydrocarbon production industry (wells and risers). It is of increasing importance for engineers to be able to model the contents of these pipelines in detail.

Coventry University has a leading capability in Electrical Capacitance Tomography (ECT), a technology that can provide very high resolution 2D data relating to multiphase flow in pipes. We would like to couple these 2D planes using proper orthogonal decomposition (POD) to provide information about the intervening multiphase flowfield. Validation data is required for the development of the novel methodologies necessary to achieve this coupling. To this end, we would like to produce a series of highly-resolved large eddy simulations (LES) of multiphase pipe flow. Our ECT devices are capable of providing very high resolution, time-resolved phase, density and velocity data for each of the 2D sample planes. The simulations will use this data as an inlet boundary condition.

Coventry University will leverage its extensive expertise in the development of LES boundary conditions to produce these high-resolution simulations. The open-source library of CFD applications and utilities, OpenFOAM, will be used to solve the simulations, using Coventry University and FMFM’s HPC and supercomputing facilities.

 

ABOUT THE CENTRE/DEPARTMENT

The Flow Measurement and Fluid Mechanics Faculty Research Centre undertakes fundamental and applied research into industrially-relevant complex flows including:

  • Smart Pipes, Vessels and Advanced Sensors
  • Process Tomography and Process Nowcasting
  • Fluid Mechanics of Complex Flows
  • Advanced Computing
  • Clean Combustion
  • Reservoir modelling

Flow measurement is an integral and vital part of many industrial processes. Plant control, product quality and safety systems are often underpinned by the need to measure flows of liquids, gases and solids. Trade of fuels, industrial feedstock and chemical products relies on accurate measurement of flow. Flow measurement is an essential element of all modern industrial societies.
