On-the-fly Reduced-Order Modeling of the Filter Density Function with Time-Dependent Subspaces
Aidyn Aitzhan, Peyman Givi, Hessam Babaee
A dynamical low-rank approximation is developed for reduced-order modeling (ROM) of the filtered density function (FDF) transport equation, which is utilized for large eddy simulat…
