Model & approach
- Compare existing and revised reservoir geometry under the same port conditions
- Define streamlines, mixing regions and qualitative residence paths as assessment criteria
Project study
Hydraulic-reservoir flow-path comparison
The study scope covers steady flow in two reservoir geometries, focusing on short-circuit paths, mixing regions and residence behaviour relevant to deaeration.
CFD simulationHydraulic-reservoir flow paths
Engineering question
Return and suction paths had to limit undesirable short-circuiting and make functional use of the available reservoir volume.
Boundary conditions
- Steady single-phase liquid flow
- Project-specific port, filter and bypass states
Assessment focus
- Flow paths between return and suction ports and use of the reservoir volume
- Effect of reservoir geometry on mixing regions and qualitative residence paths
Study objective
The objective was to establish a consistent basis for selecting flow routing and reservoir geometry.
