From simulation to confident design decisions — faster.
We model, simulate, and analyse so your team spends less time on rework and more time building with confidence.
Book: Computational Design and Optimization of Supersonic Intakes
Published by Routledge / CRC Press (Taylor & Francis) in November 2025. Co-authored with Dr. Ik Soo Park and Dr. N. Ananthkrishnan. 184 pages, 110 colour illustrations. The definitive treatment of the full supersonic intake design chain — from analytical methods and CFD to surrogate-model-based multi-objective optimisation.
- 9 chapters covering external, mixed, and conical intake geometries
- Kriging/MOGA multi-objective optimisation with Axiomatic Design Theory
- Reduced-Order Aerodynamic Model (ROAM) with open-source MATLAB code
- CFD methods: RANS, FANS, turbulence modelling, grid convergence
- 3D intake performance analysis at off-design conditions
Transition Modelling & Boundary Layer Analysis
Accurate prediction of laminar-to-turbulent transition is critical for drag estimation, heat transfer, and structural integrity. We develop and validate local-correlation-based zero-equation transition models suitable for complex 3D geometries in aerospace applications.
- Local-correlation zero-equation models (published in Computers & Fluids and AIAA Journal)
- Dynamical-systems stability analysis of RANS transition closures
- Validation against canonical flat-plate and turbomachinery cases
- Integration with in-house and commercial RANS solvers
- Turbomachinery transition analysis (ASME/AIAA conference work)
High-Speed Flow Control & Passive Devices
Reducing shock-wave / boundary-layer interaction losses in transonic and supersonic regimes requires carefully designed passive control devices. Our published research covers micro vortex generators, porous media, and their application to drag reduction in high-speed flows.
- Ramp-type micro vortex generator design and optimisation
- Swirl centre tracking for vortex characterisation (AIAA Journal, 2018)
- Porous-medium drag reduction in transonic SWBLI (Shock Waves, 2021)
- Tandem vortex-generator effectiveness at high Mach numbers
- Supersonic intake flow-phenomenon investigation
Multi-Objective Optimisation & Supersonic Intake Design
Combining Axiomatic Design Theory with Kriging surrogate modelling and MOGA, we deliver systematic, multi-objective optimisation frameworks for aerospace components with competing design requirements. This expertise forms the backbone of our published textbook.
- Multi-objective optimisation of supersonic intakes (AIAA AVIATION 2023)
- Kriging / MOGA surrogate-based design space exploration
- Axiomatic Design Theory for structured requirement decomposition
- FEST-3D open-source CFD solver (JOSS 2020)
- Convergence studies with two-equation RANS turbulence models
