Mission description
The challenge of this project was to control the specific thermo-aerodynamic phenomena induced by cooler discharge, as well as the evolution of the various thermal plumes.
CFD studies enabled us to visualize the various thermo-aerodynamic phenomena as a function of different wind orientations, which in turn enabled us to optimize the HVAC treatment systems.
Creating a digital twin
The digital twin of the data center studied in CFD includes air volumes, all generator sets, external air coolers and walls in contact with the outside.
All HVAC systems are modeled.
The digital twin also includes the surrounding buildings, which have been carefully modeled in order to obtain the most accurate evolution of thermal plumes under different wind orientations, and thus quickly identify potential thermal problems.
By analyzing these results from a global or local perspective, we can propose solutions that adapt to the various problems identified.
All generator sets have been CFD-modeled using the digital twin.
Motors, chimneys, heat extraction fans, equipment systems and electrical cabinets are all taken into account in the study.
The refinement of the CFD resolution provides a complex temperature distribution that is representative of reality.
Certain specific phenomena were identified during the study, leading to design work to resolve these issues.
Design readjustment
CFD simulations have made it possible to represent areas of high temperatures at all points in space .
This advantage of simulation has thus allowed us to know precisely the loop zones between the air expelled by the air coolers and the air that they breathe back.
The results obtained allowed us to conclude that the thermo-aeraulic dynamics of the original design could cause overheating of the cooling system .
In addition, these results made it possible to review the original design and implement appropriate solutions .
Why use CFDs?
By using a CFD study, it is possible to analyze, check and correct, if necessary, potential errors during the design. This fast, precise method reduces design time and ensures concrete and safe results .
Integrating a CFD study during its design stage means calling on professionals to ensure that no problems arise in the future.
