Computational Fluid Dynamics (CFD)

Computational Fluid Dynamic

Specialized CFD & Microclimate Simulation Services (PHOENICS)

We utilize PHOENICS, a world-renowned, general-purpose Computational Fluid Dynamics (CFD) software engine to analyze complex environmental conditions. To model thermal environments and critical safety parameters in mission-critical facilities and high-occupancy venues.

Our engineering capabilities focus intensely on Data Halls / Mission Critical Data Centres and Large-Scale Auditoriums / Theatres, Outdoor environment flow direction / circulation condition, etc.

We execute a highly structured, data-driven simulation workflow to capture local airflow complexities, eliminate thermal blind spots, and validate performance-based designs.

Auditorium geometry and ventilation model

Technical details

Data hall metrics

Precise server rack arrangements, IT heat dissipation loads (kW per rack), raised underfloor plenums, perforated tile opening ratios, CRAC/CRAH airflow supply curves and ventilation wall arrangements.

Auditorium metrics

Structural geometry, stepped seating, occupant metabolic heat loads, and overhead or underfloor displacement ventilation grille arrangements.

Physical boundary inputs

Surface roughness, structural thermal properties, jet flow angles, heat energy inputs and outputs, and buoyancy constraints, using the CAD / Revit import interfaces described in the supplied service brief.

02 / PHOENICS

Steady-state equilibrium modelling

Analyse how airflow and temperature settle under sustained operating conditions.

Airflow paths within the auditorium model

Technical details

Coupled flow & heat transfer

Numerical iterations solve the equations for mass, momentum and heat transfer together.

Equilibrium verification

Steady-state fluid and thermal modelling examines how temperatures stabilise at maximum operating capacity and how continuous thermal loads interact with mechanical extraction.

Failure scenarios

Assess airflow redirection, local hot spots and temperature increases under disrupted system conditions, such as partial cooling unit failure, recirculation or airflow short-circuiting.

03 / PHOENICS

Visualised results & interpretation

Turn simulation outputs into clear visual evidence and actionable engineering advice.
