Selected technical projects demonstrating our capabilities across high-speed aerodynamics, CFD methodology, and design optimisation. Where client engagements are subject to confidentiality, only the technical domain is listed.
Supersonic Intake Multi-Objective Optimisation
Domain: External aerodynamics / intake design Methods: Kriging surrogate modelling, MOGA, Axiomatic Design Theory, RANS CFD
Developed and applied a full optimisation framework for arbitrary supersonic intake geometries. Functional requirements and design parameters were decomposed using Axiomatic Design Theory before a Latin Hypercube sampling study was run with high-fidelity RANS CFD. A Kriging surrogate model was fitted and a Multi-Objective Genetic Algorithm (MOGA) used to generate Pareto-optimal configurations trading total pressure recovery against pressure drag.
Results formed the basis of two conference papers (AIAA AVIATION 2023) and Chapter 7 of the textbook Computational Design and Optimization of Supersonic Intakes (Routledge, 2025).
Laminar-to-Turbulent Transition Modelling
Domain: Boundary layer / turbomachinery aerodynamics Methods: Local-correlation zero-equation RANS, dynamical systems analysis
Developed a local-correlation-based zero-equation transition model compatible with standard two-equation RANS solvers. The model encodes transition onset as a function of shape factor, free-stream turbulence intensity, and pressure gradient — with no additional transport equations and negligible solver overhead.
A dynamical-systems stability analysis of the transition closure identified spurious fixed points in common intermittency formulations responsible for convergence failures. The corrected model was validated against flat-plate and turbomachinery test cases.

Porous-Medium Passive Flow Control for Transonic SWBLI
Domain: Transonic aerodynamics / passive flow control Methods: RANS, porous media boundary conditions
Investigated porous-surface passive control as a method of reducing shock-wave/boundary-layer interaction (SWBLI) losses in transonic regimes. The porous medium allows controlled mass transfer across the interaction region, attenuating the peak adverse pressure gradient and delaying separation without discrete protrusions or moving parts.

Micro Vortex Generator Design — Ramp and Wedge Types
Domain: High-speed boundary layer / flow control Methods: RANS, swirl centre tracking post-processing
Evaluated ramp-type and wedge-type micro vortex generators for boundary-layer re-energisation upstream of high-speed shock-wave/boundary-layer interactions. Introduced a swirl centre tracking methodology to quantify vortex strength and decay trajectory from CFD data — enabling systematic comparison across device geometries and operating conditions.
A follow-on study characterised tandem vortex-generator arrangements for stronger interaction regions.

FEST-3D — Open-Source Structured CFD Solver
Domain: Computational methods / solver development Stack: Modern Fortran, CGNS, pyCGNS
Lead developer of FEST-3D (Finite-volume Explicit STructured 3-Dimensional solver): a modular, multi-block structured RANS solver supporting MUSCL/WENO reconstruction, explicit Runge-Kutta time integration with local time-stepping, and pluggable turbulence/transition models. Used as the primary in-house solver for the intake optimisation and transition modelling studies above.
