About Bernardas
I am a CFD and simulation specialist with a PhD in Engineering and industrial experience spanning product development, engineering consultancy and applied sciences.
Over the last decade I have applied Computational Fluid Dynamics (CFD), multiphase-flow modelling and numerical methods to solve complex engineering problems across water, environmental, product-development and applied-science applications. My experience includes product innovation at Hydro International, nearly three years as a Senior CFD Modeller at Jacobs, and consultancy work involving multiphase flow, particle/fluid systems, high-concentration suspensions and population balance modelling.
I support clients with:
- CFD model development and analysis
- OpenFOAM, STAR-CCM+ and simulation workflow development
- Multiphase flow and particle transport modelling
- Design evaluation, optimisation and feasibility studies
- Technical reporting and interpretation of simulation results
- Python-based data processing and post-processing workflows
- Independent technical review and troubleshooting of existing CFD models
My focus is on developing robust modelling approaches, interpreting complex simulation results and translating technical analysis into practical engineering insight that supports design, product-development and decision-making activities.

Education
- PhD in EngineeringUniversity of Exeter2018PhD research focused on the computational modelling of struvite precipitation processes using Computational Fluid Dynamics (CFD) and Population Balance Modelling (PBM). Developed coupled CFD–PBM approaches to investigate the interaction between fluid flow, mixing, supersaturation, nucleation, crystal growth and particle transport in wastewater treatment systems. The work involved numerical method development, model validation, sensitivity analysis and interpretation of complex multiphase processes. Key areas: OpenFOAM, Population Balance Modelling, multiphase flow, particle transport, numerical methods, HPC, Python-based data processing and model validation.
- MPhys in Mathematical PhysicsUniversity of Edinburgh2014Integrated Master’s degree providing a strong foundation in applied mathematics, physics and computational problem-solving. The programme developed my grounding in mathematical modelling, numerical methods, classical and quantum mechanics, statistical physics and analytical problem-solving. This background underpins my later work in CFD, multiphase-flow modelling, scientific computing and engineering simulation. Key areas: applied mathematics, mathematical modelling, numerical methods, physics, scientific computing, analytical problem-solving.
