Computational fluid dynamics (CFD) consulting services

Computational Fluid Dynamics (CFD) provides engineering teams with detailed insight into airflow, heat transfer, mixing, and multiphase behaviour that simplified design rules and steady-state calculations cannot capture.

At NavierFlow US, we deliver high-fidelity CFD analysis to help clients understand how real systems behave under real operating conditions. Our work supports better engineering decisions across design, optimisation, troubleshooting, and operational change.

CFD is most valuable when systems are complex, tightly coupled, or operating close to performance limits. In these cases, understanding flow interactions, thermal behaviour, and transient effects is essential for reducing risk and improving reliability.

Below are some of the core CFD consulting services we provide.

---

Airflow and ventilation modelling

We provide CFD analysis of internal and external airflow to assess performance, identify inefficiencies, and support robust design decisions across a wide range of applications.

Typical studies include:

• Industrial ventilation and enclosure airflow
• Gas turbine intake and exhaust systems
• Data center airflow and containment performance
• HVAC airflow distribution and recirculation
• External wind effects and building aerodynamics
• Smoke movement and contaminant transport

Our simulations capture flow separation, recirculation, pressure imbalance, and interactions with surrounding structures that are often missed by simplified design approaches.

Thermal and heat transfer analysis

Thermal performance is often governed by complex interactions between airflow, equipment behaviour, and boundary conditions. CFD allows these effects to be evaluated as an integrated system rather than in isolation.

We support:

• Electronics and equipment cooling
• Data center thermal performance and resilience
• Process heat rejection and thermal comfort
• Steady-state and transient thermal scenarios
• Short-break and ride-through assessments
• Chiller, CRAH, CRAC, and heat exchanger interactions

This enables targeted improvements to energy efficiency, operational margins, and long-term reliability.

Multiphase, reacting, and mixing flows

Many industrial systems involve more than a single fluid phase or include mixing, phase change, or chemical reactions that directly influence performance.

Our CFD capabilities include:

• Gas-liquid and liquid-solid flows
• Spray, droplet, and particle tracking
• Mixing and residence time analysis
• Reactive and non-reactive species transport
• Concentration uniformity and segregation risk

These studies are often critical for process safety, emissions control, and consistent system operation.

System integration and coupled modelling

CFD rarely operates in isolation. We integrate CFD with system-level modelling to evaluate performance across full operating envelopes and transient scenarios.

Our approach includes:

• Boundary condition mapping between 1D and 3D models
• Coupling CFD with system simulation tools such as OLGA and Flownex
• Assessment of operational transients and control strategies
• Scenario-based “what-if” analysis

This combined methodology allows both local flow behaviour and system-wide interactions to be assessed consistently.

Design optimisation and engineering decision support

CFD is a decision-support tool, not just a visualisation exercise. Our focus is on delivering clear, defensible engineering conclusions that can be acted upon.

We use CFD to:

• Compare design options objectively
• Optimise layouts, geometries, and operating strategies
• Identify root causes of performance issues
• Reduce redesign, retrofit, and commissioning risk
• Support investment and operational decisions with quantitative evidence

Industries we support

Our CFD consulting services support a wide range of sectors, including:

• Power generation and refining
• Oil and gas
• Data centers
• Wastewater and municipal infrastructure
• Industrial and critical facilities

Each sector presents unique challenges, but the underlying physics and engineering rigour remain the same.
