Compressible & turbomachinery CFD
Gas dynamics · RANS · multi-fidelity design
A coherent thread through supersonic nozzle design, axial-compressor synthesis, high-pressure turbine blade RANS, and first-principles Euler solvers, graduate and early-career portfolio work that underpins later Oxford ECAT campaigns on turbomachinery deterioration.

Why this cluster exists
Several strong compressible-flow and turbomachinery projects lived only inside the projects catalogue: discoverable as cards, but without a thematic home explaining how supersonic gas dynamics, compressor synthesis, and HPT blade RANS connect. This page is the editorial index: it routes readers to evidence, methods, and curriculum without duplicating full project logs.
Subject threads
| Thread | Engineering question | Project evidence |
|---|---|---|
| Supersonic gas dynamics | How do you design a minimal-length nozzle for uniform Mach 3 exhaust? | MOC supersonic nozzle |
| Axial compressor synthesis | How do you balance stage loading, diffusion limits, and transonic tips in a multi-stage machine? | 9-stage compressor |
| HPT blade aerodynamics | How do meanline, throughflow, Q3D, and 3D RANS rank for secondary-loss prediction? | HPT blade design |
| Numerical methods | What discretisation and shock-capturing choices stabilise transonic Euler solvers? | C++ Euler solver |
| Surrogate-assisted design | When can ML replace exhaustive 3D sweeps in compressor redesign? | Compressor ML redesign |
Project evidence
Minimal-length supersonic nozzle (MOC)
Shock-free Mach 3 exhaust via characteristic-net convergence, isentropic area-ratio targeting and discretisation study.
9-stage axial compressor aerodynamic synthesis
Free-vortex radial equilibrium, Lieblein diffusion limits, and transonic first-stage tip Mach management for PR 7.
HPT blade aerodynamic design
Meanline → throughflow → Q3D → 3D RANS hierarchy for a four-stage turbine with subsonic compressibility limits.
Computational fluid dynamics solver development
Runge-Kutta time integration, JST artificial viscosity, and local CFL management, validated on a supersonic bend case.
Methods & foundations
- CFD-experiment validation: how simulation claims are paired with measurement (Oxford HPT programme)
- Aerothermal engineering methods: cross-cutting experiment and CFD workflows
- Dimensionless groups reference: Reynolds, Mach, and similarity checklists for scaling arguments
- Fluid mechanics curriculum: dimensional analysis and viscous-flow modules underpinning compressible similarity
- Dimensional analysis module: Buckingham Pi reduction for aerodynamic test planning
In preparation
Honest next builds, synthesis pages that add argument, not duplicate project cards.
- RANS discipline for transonic turbine passages: reference article synthesising compressor, nozzle, and HPT blade projects (see articles pilot)
- Compressible flow curriculum module: bridge from viscous-flow modules to turbomachinery research (see curriculum roadmap)
