Our Services
Using the powerful OpenFOAM® CFD solver on the University of Southampton’s cutting-edge supercomputer, Iridis 6, enables us to swiftly conduct extensive, high-fidelity simulations. We have conducted a very wide variety of CFD studies ranging from our traditional work for naval architects to pump flow, environmental modelling and more. Our CFD tools deliver world-leading simulations, validated against our extensive historical database of experimental testing, ensuring unmatched accuracy and efficiency. Some CFD techniques we can offer include:
- Reynolds Averaged Navier Stokes (RANS)
- Volume of Fluid (VOF) free surface modelling
- Unsteady and Detached Eddy Simulations (DES)
- Coupled Fluid-Structure Interaction (FSI) modelling
- Urban micro climate studies
- Propeller, turbine and other rotational flows
Smart Analysis
Our CFD engineers go beyond delivering data. We transform complex results into actionable insights, helping you solve real engineering problems with precision and clarity
Speed
With access to the Iridis supercomputer, we perform more simulations in less time, enabling deeper optimisation studies and delivering the best possible solutions faster.
Hydrodynamics and hull form optimisation
Hydrodynamics and Hull Form Optimisation
Where wave drag is important we recommend free-surface simulations, using RANS based CFD with a volume-of-fluid (VOF) method to represent the air and water phases.
We offer hull form evaluation and optimisation, by conducting CFD simulations at the desired speeds and comparing to our extensive database of towing tank results. Driven by the naval architect’s design requirements, our engineers can provide expertise in improving the lines throughout the optimisation cycle, using CFD to validate each step or design iteration.
Outcomes of a typical hull form analysis and optimisation study include:
- Effective power and resistance, wave and viscous drag
- Dynamic behaviour (running trim, heave and wetted surface area)
- Wave pattern and elevation
- Surface flow lines and pressure distribution
- Prediction of appendage drag and hull/appendage interaction
- EEXI / EEDI calculations and assessment
- Wake surveys and effect of propulsion on local flow via momentum disc modelling
Aerodynamic Studies
Aerodynamic Studies
We offer an extensive aerodynamic analysis and performance prediction capability. Modelling capabilities include unsteady and twisted flow, as well as state-of-the-art prediction of turbulent behaviour (using Detached Eddy Simulation, or DES), allowing accurate evaluation of aerodynamic forces and flow-paths.
Typical studies that can be conducted include:
- Aerodynamic efficiency of sails and wings
- Performance prediction in unsteady conditions
- Prediction of aerodynamic forces on superstructures, buildings and microclimate modelling
- Turbine performance prediction for thrust or energy production
- Renewable Energy Device optimisation
- Vortex Induced Vibrations (VIVs), flutter and galloping analysis
- Heli-deck environment studies
CFD Combined with Experimental Methods
CFD Combined with Experimental Methods
We have the unique capability of offering both experimental and CFD analysis allowing us to provide an impartial assessment regarding the suitability of each method.
We excel in integrating these approaches when necessary, leveraging their respective strengths to optimise the design process. Processes such as PIV and LDA are used to enhance validation data gained from the experimental testing, ensuring comprehensive and accurate insights.
