Abstract

In this work, a hybrid methodology for simulating turbulent flows is presented, combining the incompressible Schrödinger flow (ISF) model with large eddy simulation (LES). ISF captures large-scale coherent structures, while LES suppresses small-scale fluctuations and introduces model dissipation. The implementation targets HPC environments with hybrid parallelism and energy efficiency. The study addresses the foundations of hybridization, algorithmic integration, and numerical experiments, confirming the practical significance of the approach.
