Parallel turbulent Lattice Boltzmann solver

Context

High-fidelity simulation of turbulent flow demands numerical methods that stay accurate and stable at scale. The Lattice Boltzmann method offers a route to massively parallel performance — if the formulation, boundary treatment, and refinement strategy are built with the target hardware in mind from the start.

My role

I was the sole developer — from mathematical formulation through validated, parallelised implementation, as the core of my PhD in mechanical engineering.

Approach

• Lattice Boltzmann formulation suited to turbulent flow regimes.
• Parallelisation across CPU and GPU architectures.
• Adaptive grid refinement to concentrate resolution where the flow demands it.
• Systematic validation against canonical benchmark flows.

Outcome

A working research solver underpinning the doctoral thesis and journal publications, and the foundation for later coupled-physics work.
