Start with your question
Why visitors arrive: You want a derivation, calibration model, or methods reference - shorter than a paper, more precise than a blog post.
Your question: Which technical notes exist for instrumentation, turbomachinery, or thermal design?
You may also be asking
- Where is probe uncertainty worked out?
- Is there thermography data reduction guidance?
- How do notes link to publications?
Where to go next
- Instrumentation theme — Index for probe and metrology notes
- Uncertainty fundamentals — Start here if metrology vocabulary is new
- Pneumatic probes overview — Choose 3-hole vs 5-hole and calibration path
- Publications — Formal research using these methods
Technical notes
Short-form technical documentation — derivations, calibration models, and uncertainty workflows supporting publications, projects, and the engineering knowledge platform.
- Focus: Mathematical derivations, signal processing, and calibration algorithms
- Author: Lucas Rey — Oxford DPhil aerothermal engineer · ORCID · About · Publications
- Format: Compact reference documents typeset with MathJax for technical clarity
- Curriculum: Structured fluid mechanics modules live on the fluid mechanics curriculum hub — foundational Pi-group tables also on the dimensionless groups reference
Knowledge clusters
Notes are grouped by research thread so related publications, projects, and tools stay discoverable from one canonical index — not scattered across the site.

- Dimensional analysis module — full derivations in the curriculum
Published notes
Each note consolidates derivations and operational workflows into a durable reference. Notes link forward to projects and publications where the methods are applied, and to calculators where correlations are implemented interactively.
HPT transient thermography
Data-reduction and uncertainty posture for transient infrared thermography on engine-scale HPT hardware — ECAT workflow, Biot-consistent interpretation, and pairing with RANS validation.

Seven live notes — additional derivations are added as research workflows are formalised.
In preparation
These notes are scoped from active project and publication work — listed here so the hub reflects honest roadmap status, not a single finished item.
- 5-hole probe Monte Carlo suite — companion to the multi-facility calibration project and Oxford probe publication track
Structured curriculum
Long-form fluid mechanics teaching material — dimensional analysis, viscous flow, and matched problem sets — is maintained as a dedicated curriculum path rather than as notes. The modules were developed during teaching in Barcelona (IES Abroad) and are published as first-principles learning resources.
Available for technically rigorous R&D and institutional collaboration.
