Abstract :
This research presents a hybrid turbulence modeling framework that couples fractional-order Navier-Stokes
equations with a machine learning-based subgrid-scale stress closure model. The objective is to enhance the accuracy of
turbulent flow simulations by incorporating long-range memory and non-local effects via fractional calculus, alongside
neural network-inspired closures. A simplified 1D fractional-order Burgers' equation is used with a synthetic ML-based
stress term to illustrate the method. Results show improved flow representation, highlighting the model’s potential for
broader applications in fluid mechanics.
