Our Company Awarded EuroHPC Benchmark Access

Design and Simulation Tech. is proud to announce that our proposal to the EuroHPC Benchmark Access Call has been successfully accepted. We have been awarded 2,000 node hours on the MeluXina CPU, enabling us to conduct benchmarking studies for our advanced Conjugate Heat Transfer (CHT) model. This model is used for the realistic simulation of CPUs as heat sources in data centers, a crucial component of effective thermal management in today’s high-performance computing environments.

Our focus will be on simulating two-phase direct-to-chip liquid cooling, a cutting-edge cooling technology that transfers heat directly from the CPU using a liquid that undergoes phase change. This method is increasingly recognized as a highly efficient solution for managing heat in data centers, offering substantial energy savings.

This allocation will allow us to perform high-precision simulations, aiming to validate and optimize the thermal performance of data centers equipped with two-phase direct-to-chip liquid cooling systems. The numerical studies will provide insights into improving energy efficiency at our pilot sites, aligning with our broader commitment to innovation and sustainability.

This milestone marks an important step forward in advancing data center thermal management technologies, and we look forward to collaborating with our partners in the HEATWISE project to deliver impactful results.

CHT modeling of forced convection over a heated pipe

A Conjugate Heat Transfer (CHT) thermal model was developed and validated on the forced convection problem at our paper. Accurate calculation of the Nusselt number on the cylinder is improtrant to the validation of the numerical results with the experimental data. In this study, a function object is developed for the calculation of the Nusselt number on the cylinder based on OpenFoam libraries. See the following link for the source code.
