Engineering Digital Twin

Decision-ready digital twins for thermo-fluid and energy systems—combining credible models, physical measurements and operational data to support design, troubleshooting, monitoring, optimisation and scale-up.

Core capability: thermo-fluid engineering with fit-for-purpose modelling, targeted measurement and a clear pathway from evidence to action.

What we help you achieve

De-risk design decisions

Predict performance, identify sensitivities, and define safe operating windows before committing to fabrication or procurement.

Troubleshoot performance issues

Find root causes of hotspots, maldistribution, pressure-drop penalties, vibration drivers, or unexpected degradation.

Support scale-up & optimisation

Translate lab results to pilot/operation using models that capture the dominant physics and quantify uncertainty.

Typical use cases

Thermo-fluid systems

  • Heat exchangers, heating/cooling layouts, thermal management
  • Flow distribution, mixing, pressure drop, separation
  • Boundary-layer driven performance limits and hotspots

Phase-change & energy systems

  • Phase-change materials for storage/transport
  • Boiling / condensation / interface-driven behaviour (as required)
  • Hydrogenation / metal-hydride storage: thermal management and cycle optimisation

Aerodynamics & turbomachinery

  • External/internal aerodynamics for performance and noise
  • Turbulence modelling choices that match decision needs
  • Turbomachinery: performance prediction and loss drivers (as scoped)

Measurement, monitoring & field tests

  • Data acquisition strategy and instrument selection
  • Calibration and post-processing workflows
  • Advanced diagnostics (e.g., LIF, PIV) when appropriate

From physical system to living model

Measurement-informed digital twins

An effective digital twin is more than a simulation. It connects a physical asset or experiment to a computational representation, then uses measured evidence to calibrate, validate and update that representation as conditions change.

01

Observe

Measure the physical system at the spatial and temporal resolution needed for the decision.

02

Integrate

Synchronise, calibrate and quality-check measurement, operational and contextual data.

03

Model

Combine the data with CFD, reduced-order, analytical or data-driven models.

04

Act

Use the twin for monitoring, diagnosis, forecasting, optimisation and decision support.

Point and distributed sensors

Temperature, pressure, flow, vibration, acoustic, humidity, light and other sensors provide continuous operating data. Sensor selection, placement, calibration, uncertainty and sampling rate are designed around the quantities the twin must infer or predict.

PIV — Particle Image Velocimetry

PIV provides non-intrusive velocity fields for resolving flow structures, validating CFD and developing reduced-order representations. Time-resolved or phase-locked measurements can capture transient and periodic behaviour.

LIF — Laser-Induced Fluorescence

LIF maps scalar fields such as temperature or concentration. When combined with PIV, it links transport behaviour to the underlying flow and provides rich validation data for coupled thermo-fluid models.

Infrared thermography

Thermal imaging captures spatial surface-temperature distributions, hotspots and transient thermal response. Emissivity, reflections, viewing geometry and reference measurements are managed to obtain defensible quantitative data.

Integrated by design: these measurements can be combined with laboratory tests, field observations, existing control-system data, CFD, LBM, reduced-order models, system identification, uncertainty quantification and machine learning. The result is a fit-for-purpose twin with traceable assumptions and known confidence—not simply a dashboard or a static model.

Methods we use (fit-for-purpose)

Core modelling

  • CFD workflows for flow and heat transfer (Eulerian methods)
  • Verification-minded setup: assumptions, boundary conditions, sensitivity checks
  • Validation planning using available measurements and operational data

Advanced techniques (when warranted)

  • Lattice Boltzmann Method (LBM) for specialised flow/transport contexts
  • Discrete Element Method (DEM) for particulate/granular interactions
  • Smooth Particle Hydrodynamics (SPH) for free-surface and complex interface behaviour

Key principle: we choose the minimum fidelity that answers the decision safely—then increase fidelity only if it changes the decision.

Deliverables you can use

Decision brief

What we found, what it means, and what to do next—written for stakeholders.

Technical pack

Assumptions, inputs, model setup, sensitivity checks, and a clear audit trail.

Handover & uplift

Runbook + optional training so your team can extend the work internally.

What we need from you (to start)

Minimum inputs

  • The decision you’re trying to make (A vs B / target / pass-fail)
  • Geometry / drawings (even rough), operating ranges, and constraints
  • Any available data (flows, temperatures, pressures, duty, material properties)
  • Deadline and definition of “success”

If available (helps a lot)

  • Known failure modes / observed issues (photos, thermal images, logs)
  • Previous calculations/simulations and what you did/didn’t trust
  • Site limitations (measurement access, sensor limits, safety constraints)
