CFD Modelling
CFD (Computational Fluid Dynamics) modelling of a data centre machine room involves creating a three-dimensional mathematical model of a physical space using computational fluid dynamics methods. The objective is to evaluate the efficiency of heat exchange in the data centre, identify design features of the room, and assess the impact of thermal load on airflow distribution.
Arm-Architect delivers modelling results covering the microclimate characteristics of the machine room — temperature, pressure, humidity, airflow velocity, and direction. CFD modelling of diesel generator operation and assessment of its impact on other data centre systems. Design and analysis of data centre server rooms. The model verifies the viability of engineering solutions and the correctness of equipment selection at early design stages. Airflow and resource analysis: temperature maps across three planes help identify room design features and evaluate engineering equipment selection. Data centre room optimisation: the verified model is suitable for virtual tests involving load relocation or addition, and engineering system setting changes. Identification of "hot spots" where cooling is insufficient, enabling efficient placement decisions for new servers.
Key stages of CFD modelling include: Creating the base model — populated with elements corresponding to the geometry of the actual or planned space. Scenario modelling — for example, analysis of the underfloor plenum space and modelling of various operational scenarios. Model verification against real data — the model's predictions are checked against averaged readings from autonomous sensors.
Specialised software designed for data centre design and simulation is used for CFD modelling of the machine room. TileFlow creates a computer model of the data centre and uses a convection calculation method to produce airflow distribution maps and pressure/temperature profiles.
