<p><font size="4"><span style="font-family:verdana,sans-serif">Fluid-structure interaction (FSI) problems are ubiquitous in engineering
and biological/medical fields. Efficient modeling of FSI problems not
only helps to visualize flow fields, but also improves the device design
by experimenting with virtual geometries created on a computer. In
this talk, I will present an efficient computational framework utilizing
the immersed boundary (IB) technology for modeling FSI problems for a
range of applications. First, I will introduce the IB methodology to
resolve FSI problems. Later, I will focus on FSI applications in the
areas of aquatic locomotion, and multiphase flows. For aquatic
locomotion, I will answer two fundamental fluid mechanics questions.
The first question pertains to splitting of hydrodynamic forces into
drag and thrust for an undulatory swimmer.
Undulatory swimmers do not have demarcated drag and thrust producing
spatial regions, unlike an airplane’s fuselage (drag) and propellers
(thrust). Using fully resolved simulations, I will show that it is still
possible to split drag and thrust for undulatory swimmers even at high
Reynolds number. The second question pertains to the convergent
evolution of optimal specific wavelength of elongated fins observed in
various vertebrates and invertebrates. These species diverged on the
tree-of-life millions of years ago. Using simulations, we find that the
observed specific deformation pattern of the fins is thrust maximizing,
thereby increasing their chance of survival. For multiphase flows, I
will present results on a coupled level set and IB method to simulate
three phase (solid, gas, and liquid) flows using a strongly coupled
velocity-pressure flow solver. Finally, I will present applications of
this novel multiphase solver in modeling wave energy converters and
windmill simulations.</span></font></p>
