Projects

Coupled curvilinear immersed boundary (CURV-IB) and rotation free finite element (RF-FE) method, 2015

The CURV-IB-RF-FE allowed to simulate cardiovascular problems as an interaction of deformable heart leaflets with pulsate blood flow in a real aorta. Using this approach, computational results that revealed major differences between the TAV and BAV flow patterns had been obtained. (Gilmanov, et al., 2015, JCP)

Rotation free finite element (RF-FE) method, 2013

with triangular thin-shell finite element formulation which employs only translational degrees of freedom had been developed. The formulation allowed for large deformations, and it was based on the nonlinear Kirchhoff thin shell theory. (Stolarski, et al., 2013, Int. J. Numer. Meth. Engng)

Hybrid Cartesian Immersed Boundary Method, 2005

A powerful numerical method for solving the 3D, unsteady, incompressible Navier–Stokes equations in Cartesian domains containing immersed boundaries of arbitrary geometrical complexity moving with prescribed kinematics had been developed. This method allowed to simulate flow past an undulating fish-like body and flow past an anatomically realistic planktonic copepod performing an escape-like maneuver. Another application of this method was done in an area of cardiovascular simulations (Gilmanov, Sotiropoulos, 2005, JCP).

Dynamic adaptive mesh method, 2001

Developed an approach that solved a problem of interaction of supersonic gas flow with rigid and deformable bodies using high accuracy total variation diminishing (TVD) schemes.
The problem of deceleration of supersonic gas flow in a supersonic air intake was solved
(Gilmanov, 2001, J. Comp. Math. Math. Phys.)

The opening and closing process of the bicuspid aortic heart valve. Instantaneous contours of vorticity magnitude on a plane through the aorta plane of symmetry during the diastolic phase.

Flapping of inverted flag. Helicity iso-surfaces.

The vortex-induced vibrations of a cantilever mounted in the wake of a square cylinder. Contours of instantaneous out of plane vorticity contours for the second mode of oscillation. Re=204.
