Our Expertise in Detail
Thermal
From steady-state equilibrium to rapid transients, we understand the thermal phenomena that size your systems and underpin their safety:
- Ambient conditions — Characterisation of operating environments: temperature, humidity, and thermo-hygrometric coupling.
- Heat transfer — Modelling of all three transfer modes: radiation, conduction, and natural and forced convection.
- Dynamic behaviour — Analysis of thermal transients: grace periods, heat-up times, thermal cycling, and associated fatigue.
- Phase change — Incorporation of condensation and evaporation in your systems.
- Thermodynamic cycles — Design and optimisation of power and refrigeration cycles.
- Thermal storage — Sizing of thermal energy storage solutions (sensible and latent).
- Insulation — Assessment and optimisation of insulation performance to reduce losses and control temperatures.
Hydraulics (Gas and Liquid)
We size and optimise your networks for any fluid—water, air, industrial gases, or heat transfer fluids—from nominal operation through transient phases:
- Pressure drop & pump curves — Calculation of operating points, sizing, and selection of circulation equipment.
- Dead zone detection — Identification of poorly flushed or stagnant volumes that can cause hot spots or degradation.
- Network pre-commissioning — Balancing of branched or meshed networks through optimal positioning of control valves.
- Draining & filling — Modelling of transient phases during commissioning, shutdown, or maintenance of your circuits.
- Residence / transit times — Estimation of transport and mixing times, essential for plant operation and installation safety.
Solid Mechanics
Developing capability — we are extending our expertise into structural mechanics to provide a complete multi-physics view of your systems:
- Strength of materials — Calculation of forces, displacements, and stresses. Verification of anchors and structural connections.
- Vibration analysis — Load path analysis, natural frequency identification, and analysis of structural dynamic behaviour.
- Optimisation — Support for material selection and topology optimisation to balance performance, weight, and cost.
Multi-Physics Coupling
Our key differentiator: we model cross-discipline interactions to capture the real behaviour of your systems:
- Neutronic / thermal coupling — Modelling of feedback between neutron power and the temperature field, central to reactor safety.
- Temperature heterogeneities — Accounting for gradients and non-uniform distributions that govern design margins.
- Natural convection — Simulation of flows driven solely by thermal gradients, a key mechanism in passive safety.
- Control optimisation — Coupling instrumentation and control with process physics to align control laws with real plant behaviour.
- Thermal fatigue & expansion — Analysis of mechanical loads induced by thermal cycling: stresses, displacements, and service life.
- Thermal front & mixing — Tracking of thermal transport and mixing in networks and vessels / fluid volumes.
- HVAC cycling — Modelling of intermittent operating regimes and their impact on comfort, energy use, and equipment ageing.
