OpenFOAM heat-exchanger simulation
An OpenFOAM v2606 porous heat-exchanger study covering mesh response, transfer coefficient, hot-inlet temperature, pressure loss, flow, temperature, and heat release.

Software compatibility
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
Heat-exchanger performance depends on inlet states, flow, transfer area, resistance, fan work, porous momentum loss, mesh, numerical coupling, and the method used to extract bulk values.
Project objectives
- Adapt a licensed OpenFOAM heat-exchanger tutorial for v2606.
- Run three mesh levels with strict checks for both regions.
- Compare transfer coefficients of 5, 10, and 20 W per square metre K.
- Compare hot-fluid inlet temperatures of 360, 400, and 420 K.
- Calculate bulk temperatures, pressure losses, mass flows, enthalpy terms, hot-side heat release, stability, and limitations.
Project structure
Project components
Case generator
Creates a controlled two-region OpenFOAM case from the declared mesh, inlet temperature, transfer coefficient, and iteration count.
Porous exchanger model
Couples an air region and an overlapping hot-liquid porous region through constant inter-region heat transfer.
MRF fan
Uses a rotating-frame fan zone at 47.7 rad/s to drive the air flow.
Evidence extractor
Calculates absolute-flux-weighted bulk values, pressure loss, enthalpy terms, heat release, mesh metrics, and stability.
Verification
Checks fourteen regional meshes, seven study cases, parameter responses, figures, and repository consistency.
Methodology
Project workflow
- 01Generate
Python copies and modifies the reviewed OpenFOAM template for one declared case.
- 02Mesh
Air and porous regions are meshed, zoned, baffled, and checked with all geometry and topology options.
- 03Solve
chtMultiRegionSimpleFoam solves the coupled steady thermal-fluid fields.
- 04Extract
Patch bulk values and flow rates are converted into JSON, CSV, PNG, and SVG evidence.
- 05Compare
Mesh, transfer-coefficient, and hot-inlet trends are interpreted with the model boundaries stated.
Demonstration scenario
The exchanger runs on three meshes, at three transfer coefficients, and at three hot-fluid inlet temperatures. The student explains bulk temperature, pressure, flow, heat release, fan work, parameter trends, and why the mesh response does not establish grid independence.
Engineering
Tools and method
- Tools
- The project uses OpenFOAM v2606, Python 3, Matplotlib for subject analysis, simulation, and results.
- Case format
- Native OpenCFD OpenFOAM v2606 dictionaries, fields, region meshes, porous source terms, MRF settings, and solver logs.
- Heat transfer
- A constantHeatTransfer model uses area per volume of 200 per metre and selected transfer coefficients of 5, 10, and 20 W per square metre K.
- Flow model
- Steady compressible air and an incompressible hot-liquid porous region are coupled without resolved tubes or a solid wall.
- Analysis
- Python preserves raw data and regenerates summaries, convergence tables, tests, and 17 figures.
Testing
Evaluation
Evaluation measures
- All fourteen regional meshes pass strict checkMesh checks
- Medium case air outlet temperature 311.6809 K from a 300 K inlet
- Medium case porous outlet temperature 397.8739 K from a 400 K inlet
- Medium case hot-side heat release 1,334.04 W and air pressure loss 51.4 Pa
- Air outlet rises from 306.3526 K to 320.0666 K as transfer coefficient rises from 5 to 20 W per square metre K
- Mesh outlet temperatures of 309.1765, 311.6809, and 308.6110 K show a nonmonotonic response
- Seven automated tests passing
Project boundaries
- Only OpenCFD OpenFOAM v2606 cases are delivered.
- The exchanger is an unresolved porous representation with two overlapping fluid regions.
- No tubes, fins, separating solid, wall conduction, fouling, phase change, corrosion, vibration, or detailed headers are resolved.
- The MRF fan adds work to the air, so air enthalpy rise is not transferred heat alone.
- The three low-cost meshes show a nonmonotonic response and do not establish grid independence.
- The project is academic CFD and not equipment selection, pressure-vessel design, manufacture, rating, or certification evidence.
