CABARET on rotating meshes
Extends the CABARET conservative, low-dissipation finite-volume framework to rotating reference frames and dynamic sliding-mesh interfaces — the mesh motion required for turbomachinery, rotorcraft, and wind-turbine simulation. The central result is holding CABARET's low phase-error character across a rotating interface, where conventional ALE and sliding-mesh treatments typically reintroduce the numerical diffusion the scheme was built to avoid. This is the direct methodological link between TBL's published numerical-methods research and its turbomachinery case work — compressor stall margin and turbine secondary-flow loss both sit downstream of this result.

Implicit gradients based novel conservative numerical scheme for compressible flows
Introduces an implicit-gradient reconstruction procedure for finite-volume flux evaluation in compressible flow, computing cell-face gradients as part of an implicit solve rather than an explicit least-squares or Green–Gauss pass. The payoff is sharper flux reconstruction near shocks and steep gradients without widening the stencil — the usual cost of higher accuracy — keeping the scheme's computational footprint close to a standard second-order finite-volume method while improving shock-capturing fidelity.

Implicit gradients based novel finite volume scheme for compressible single and multi-component flows
The companion paper extending the implicit-gradient scheme from single-phase compressible flow to multi-component mixtures — flows with more than one fluid species or phase sharing a compressible field, such as multiphase combustion or gas–liquid mixtures under strong compression. Interface sharpness between components is preserved without the spurious pressure oscillations that standard schemes generate at material interfaces under compression, a known failure mode in naive multi-component finite-volume solvers.

A fourth-order CABARET scheme for Computational Aeroacoustics
Raises CABARET to formal fourth-order spatial accuracy specifically for aeroacoustic wave propagation, where phase error accumulates over the long propagation distances between a noise source and a far-field observer and directly corrupts predicted spectra. The extended compact-stencil operators reach fourth order without sacrificing CABARET's defining low-dissipation, low-dispersion behaviour, validated against canonical linear and nonlinear acoustic wave-propagation benchmarks. This is the scheme variant behind TBL's trailing-edge and jet-noise prediction work.

PhD THESIS · QUEEN MARY UNIVERSITY OF LONDON
CABARET Schemes for improved wave propagation and viscous flow modelling
The doctoral thesis unifying the CABARET scheme development programme: the dispersion and dissipation analysis underlying the flux-correction work, its extension to fourth-order accuracy for aeroacoustics, and the treatment of viscous terms needed to move the scheme from pure wave-propagation test cases toward full Navier–Stokes flow. Submitted to the Aerospace Engineering department at Queen Mary University of London, this thesis is the theoretical foundation the subsequent journal papers and the rotating-mesh extension build on directly.

Flux-corrected dispersion-improved CABARET schemes for linear and nonlinear wave propagation problems
The most-cited result in the body of work: a flux-correction procedure layered onto the CABARET scheme that suppresses spurious oscillations near discontinuities while retaining the scheme's low-dispersion accuracy on smooth wave propagation. Validated across both linear and nonlinear wave problems, this paper establishes the core scheme variant that every later extension — fourth-order aeroacoustics, rotating meshes, the PhD thesis — builds directly on top of.

Dispersion improved CABARET for computational aeroacoustics
The first application of dispersion-improved CABARET to aeroacoustic problems specifically, benchmarking phase-error accumulation over long-range sound propagation against standard second-order upwind schemes. This early result is what made the case for a dedicated high-order, low-dissipation scheme in noise prediction — the argument the fourth-order extension and thesis later formalised.

HIGH-PERFORMANCE COMPUTING
Performance of CFD solver on GPU
The earliest publication in the record, evaluating GPU acceleration of a CFD solver's core computational kernels — flux evaluation and boundary updates, both memory-bandwidth-bound operations well suited to GPU throughput — and quantifying speed-up against multi-core CPU baselines. This is the origin of the HPC and multi-core computing thread that runs through the later work, and the direct precedent for the GPU-accelerated solver runs TBL now offers on large unsteady production cases.
