WebOct 1, 2024 · Reduced-order models of stenotic vascular flow are functions of the flow velocity u ( x, t ), which influences the components of energy loss along the stenosis. In practice, these models are more conveniently expressed in terms of the volume flow rate Q ( t ), assuming incompressibility. Webreduced dynamics (corresponding to the projection stage in a linear ROM) are learned in a non-intrusive way by relying on DL algorithms; the latter are trained on a set of full order model (FOM) solutions obtained for different parameter values. We show how to construct a DL-ROM for both linear and nonlinear time-dependent parametrized PDEs.
