Reduced order modeling of convection-dominated flows, dimensionality reduction and stabilization
… methodologies for reduced order modeling of convection dominated flows. Accordingly, three main problems are addressed. Firstly, an optimal manifold is realized to enhance reducibility of convection dominated flows. We design a low-rank auto-encoder to specifically reduce the dimensionality …

Layer-averaged modeling of turbidity currents with a finite element method
… yields spurious oscillations when applied to convection-dominated flows, the dissipative-Galerkin technique which has a selective damping property, is used. In order to track the moving front numerically, a node-adding method is used for the one-dimensional problem of channelized turbidity …

Multigrid solutions of elliptic fluid flow problems
… for the accurate and economic simulation of convection dominated flows. The use of a high-order approximation to the convective transport terms found in the governing equations of motion has been investigated in conjunction with an unsegregated smoothing technique. Results are presented for a …

Finite Element Simulation of Interfacial Flows on Unstructured Meshes using a Second-order Accurate VOF Method
… Newtonian, laminar, isothermal incompressible flows, with a volume-of-fluid (VOF) technique for interface capturing. A new formulation of the pressure Poisson equation that requires the discretization of a second-order derivative is used for the flow field on a fixed Eulerian grid. This …
