Aerothermal engineering methods

Experiment · simulation · validation

How experimental aerothermal campaigns, instrumentation chains and CFD comparisons are documented and validated so that their results hold up and transfer, set out in two articles and four supporting notes. It draws on Oxford Thermofluids Institute campaigns sponsored by Rolls-Royce and on open-hardware probe benchmarking, and it sits across the instrumentation and turbomachinery deterioration themes rather than inside either.

Start with your question

Why visitors arrive: You are planning an aerothermal campaign or CFD study and need a methods framework.

Your question: How should experiments and simulations be documented, validated, and archived?

You may also be asking

  • Experiment or CFD - which article do I read first?
  • Where are uncertainty and probe resources?
  • What curriculum supports similarity scaling?

Why does a methods cluster exist?

Four clusters on this site answering four different questions. Research themes describe what is being studied, HPT holing, pneumatic probes and additive heat exchangers. Publications record formal outputs. Projects document campaigns. Methods describe how evidence is produced, the workflows that make laboratory and simulation results transferable and falsifiable. Without an explicit methods layer that practice stays buried in project folders.FOUR CLUSTERS, FOUR DIFFERENT QUESTIONS[01]Research themesdescribe what isbeing studiedHPT holing, pneumatic probes,additive heat exchangers[02]Publicationsrecord formaloutputs[03]Projectsdocumentcampaigns[04]Methodsdescribe how evidenceis producedworkflows that make resultstransferable and falsifiableWithout an explicit methods layer, that practice stays buried in project folders

The other three clusters say what was studied, published and run. This one says how the evidence was produced.

Research themes on this site describe what is being studied, HPT holing, pneumatic probes, additive heat exchangers. Publications record formal outputs. Projects document campaigns. Methods describe how evidence is produced: the workflows that make laboratory and simulation results transferable, falsifiable, and useful to designers.

Without an explicit methods layer, the discipline behind ECAT commissioning, European 5-hole probe cross-calibration, and HPT RANS pairing stays buried in project folders. This cluster documents that practice for collaborators and reviewers, synthesised from Oxford Thermofluids Institute campaigns (Rolls-Royce sponsored) and open-hardware probe benchmarking.

Experiment vs simulation validation

Both deliverables share documentation requirements but fail in different ways. Use this map to choose the right article and supporting note before scoping a campaign.

Concern Experimental aerothermal measurement CFD-experiment validation
Primary risk Biased instrumentation treated as physics Contour agreement masking wrong integrated quantities
Core artefacts Calibration files, uncertainty budgets, facility transfer benchmarks BC traceability, mesh/turbulence sensitivity, observable definitions

Integrated evidence workflow

The integrated evidence workflow in five steps: Similarity and properties, state Reynolds, Mach, Pr and Bi; Instrument model, calibrate, then propagate uncertainty; Experiment execution, the traceability chain for each measurement; Simulation pairing, lock boundary conditions and observables; Publication and archive, publications and project anchors.1Similarity and propertiesstate Reynolds, Mach, Pr and Bi2Instrument modelcalibrate, then propagate uncertainty3Experiment executionthe traceability chain for each measurement4Simulation pairinglock boundary conditions and observables5Publication and archivepublications and project anchors

Evidence in five steps: state the similarity groups, calibrate the instrument and propagate its uncertainty, trace each measurement, lock the simulation's boundary conditions, then publish and archive. Each step points to the article or note that documents it.
  1. Similarity & properties: state Reynolds, Mach, Pr, Bi using dimensionless groups and air properties
  2. Instrument model: calibrate, propagate uncertainty (fundamentals, probe note)
  3. Experiment execution: traceability chain per measurement article
  4. Simulation pairing: lock BCs and observables per validation article
  5. Publication & archive: publications hub + project anchors for reproducibility
