OpenFOAM static-mixer simulation

An OpenFOAM-only CFD study of pressure loss, residence behaviour, and passive-scalar mixing in selected static-mixer geometries.

  • OpenFOAM v2606
  • ParaView
  • Gmsh
  • Python
  • Docker

Software compatibility

OpenFOAM v2606 only

Cases are prepared for the OpenCFD OpenFOAM v2606 distribution. No ANSYS Fluent, COMSOL, STAR-CCM+, or OpenFOAM Foundation v14 files are included.

Project definition

Problem statement

A static mixer improves composition uniformity through repeated splitting and rotation but adds pressure loss, and both measures depend on geometry, Reynolds number, scalar diffusivity, and sampling plane.

Project objectives

  • Model selected empty-pipe and static-mixer geometries.
  • Simulate incompressible flow and transport of a non-reacting passive scalar.
  • Calculate pressure drop, mixing index, coefficient of variation, and residence proxies.
  • Compare geometry and flow-rate cases under identical evaluation planes.
  • Perform mesh, conservation, and scalar-balance checks.

System design

System modules

01

Geometry and mesh

Builds pipe, mixer elements, inlets, outlet, walls, refinement, and sampling planes.

02

Flow case

Solves the selected laminar or turbulent incompressible velocity and pressure field.

03

Scalar transport

Transports a bounded non-reacting scalar using documented diffusivity and inlet distributions.

04

Performance analysis

Calculates pressure loss, mixing uniformity, residence proxies, and axial development.

05

Design comparison

Applies common meshes, boundaries, planes, and uncertainty checks to alternative geometries.

Methodology

System workflow

  1. 01
    Run empty pipe

    The reference case establishes pressure and unmixed scalar behaviour.

  2. 02
    Run mixer

    A selected insert geometry is solved at the same inlet conditions.

  3. 03
    Check balances

    Flow, scalar, residual, boundedness, and mesh results are reviewed.

  4. 04
    Measure mixing

    Uniformity and pressure are calculated at fixed axial planes.

  5. 05
    Compare designs

    Geometry and flow-rate cases are ranked on mixing and pressure tradeoffs.

Demonstration scenario

An empty pipe and two static-mixer geometries receive the same split scalar inlet. The study compares cross-section uniformity and pressure loss at fixed stations and shows which geometry provides the better documented tradeoff.

Testing

Evaluation

Evaluation measures

  • Flow and scalar conservation
  • Scalar boundedness and mixing-index repeatability
  • Pressure-loss comparison with reference or empty-pipe values
  • Mesh and scalar-diffusivity sensitivity
  • Uniformity development along the mixer
  • Runtime across geometries and flow rates

System boundaries

  • Only OpenCFD OpenFOAM v2606 cases are delivered.
  • The scalar is non-reacting and the first scope excludes reactions, multiphase flow, non-Newtonian behaviour, and particle solids.
  • Residence measures are flow-based proxies unless a separate tracer calculation is included.
  • The result is not a production mixer or pressure-equipment design.
