arXiv:2605.26059v1 Announce Type: cross Abstract: Bayesian inverse design provides a principled framework for inferring aerodynamic geometries from sparse flow observations while quantifying uncertainty. However, its practical use in computational fluid dynamics (CFD) is severely limited by the cost of repeated high-fidelity simulations required for gradient-based Markov chain Monte Carlo (MCMC) sampling. While surrogate models are commonly proposed to reduce this cost, their effect on posterior geometry and uncertainty, especially for shock-dominated flows, remains poorly understood. In this
The rapid advancement of neural operators combined with the increasing computational demand for complex engineering simulations makes this research timely for improving efficiency.
This development can significantly reduce the computational cost and time required for complex engineering designs, particularly in fields like aerospace and automotive, by optimizing processes that currently rely on expensive high-fidelity simulations.
The ability to more quickly and accurately perform inverse design in computational fluid dynamics, especially for challenging shock-dominated flows, will accelerate R&D cycles and potentially lead to more optimized designs.
