CFD Simulations in HPC Immersion Cooled

SUBMER company designs, builds and installs Liquid Immersion cooling solutions for HPC, hyperscaler, datacenters, Edge, AI, deep learning and blockchain applications. SUBMER Immersion Cooling is changing how datacenters are being built from the ground up, to be as efficient as possible and to have little or positive impact on the environment around them (reducing their footprint and reducing their consumption of precious resources such as water). SUBMER was founded in 2015 by Daniel Pope and Pol Valls, to make operating and constructing datacenters more sustainable. This SHAPE project aims to increase the knowledge and expertise of SUBMER employees in the realm of CFD simulations in an HPC environment. The project also aims to demonstrate tangible benefits in terms of improved design, efficiency and effectiveness of their immersion cooling solution. The vision of SUBMER is that being able to model a reasonably close estimation to the operational behavior of their systems is key to avoiding costly mistakes, provide a better product to their clientele and greatly reducing time to market. This white paper presents the methodology employed during the project, as well as some selected results.
