- Hemodynamics of Stenosed Arteries:
The methodology uses image-based computational fluid dynamics (CFD)
simulations. It consists of the following steps:
(a) reconstruction of an anatomically realistic
geometric model of a stenosed artery from magnetic resonance
angiography (MRA) images; (b) generation of a computational
mesh; (c) direct numerical simulations (DNS) of an arterial
flow; (d) proper orthogonal decomposition (POD) analysis of
DNS-driven data for extracting meaningful clinical information.
- Immersed-Boundary Methods: We use a
direct
forcing immersed-boundary (IB) method to perform direct numerical
simulations (DNS) of turbulent flows and heat transfer in complex
geometries. Following the IB approach, we solve the governing
equations using rectangular Cartesian coordinates; both the no-slip
boundary condition and
isothermal wall boundary
condition are imposed by
introducing a direct-forcing term
into the momentum and energy
equations.
