Abstract
Optimizing gas turbines is a complex multi-physical and multi-component
problem that has long been based on expensive experiments. Today, computer simulations
can reduce design process costs and are acknowledged as a promising path for
optimization. Although the simulations of specific components of gas turbines become
accessible, these stand-alone simulations face a new challenge: to improve the quality of
the results, new physics must be introduced. Based on the simulation of conjugate heat
transfer within an industrial combustor to predict the temperature of its walls, the current
work aims at studying the scalability of code coupling on HPC architectures. Coupling
accurately solvers on massively parallel architectures while maintaining their scalability
is challenging. The strategy investigated relies on recent developments made in a generic
parallel coupler. Performance tests have been carried out until 12,288 cores on the CURIE
supercomputer (TGCC / CEA). Results show a good behavior and advanced analyzes are
carried out in order to draw new paths for future developments in coupled simulations.
