New benchmark tests operator learning for complex fluid dynamics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new benchmark for operator learning models in fluid dynamics, specifically focusing on three-phase interfacial flow. This benchmark utilizes a ternary Cahn-Hilliard-Navier-Stokes solver to generate reference data for complex scenarios like an air bubble piercing a water-oil interface. The study compares three DeepONet variants, finding that SEDONet, which uses a Chebyshev representation, significantly outperforms others in accuracy and error reduction, particularly near interfaces and after bubble breakthrough.

    Spectral-Embedded Operator Learning for Three-Phase Interfacial Flow: A Ternary Cahn-Hilliard-Navier-Stokes Benchmark

    arXiv:2608.29069v1 Announce Type: cross Abstract: Operator-learning surrogates have been benchmarked largely on single-field, single-interface problems, leaving unclear whether architectural choices validated in those settings transfer to constrained, multiphase flows. We introdu…
