Hopscotching Jellyfish: combining different duty cycle kinematics can lead to enhanced swimming performance
Tierney Baldwin, Nicholas A. Battista
Jellyfish (Medusozoa) have been deemed the most energy-efficient animals in the world. Their bell morphology and relatively simple nervous systems make them attractive to robotocis…
Swimming through parameter subspaces of a simple anguilliform swimmer
Nicholas A. Battista
Computational scientists have investigated swimming performance across a multitude of different systems for decades. Most models depend on numerous model parameters and performance…
Diving into a simple anguilliform swimmer's sensitivity
Nicholas A. Battista
Computational models of aquatic locomotion range from individual modest simple swimmers in 2D to sophisticated 3D individual swimmers to complex multi-swimmer models that attempt t…
Naut your everyday jellyfish model: Exploring how tentacles and oral arms impact locomotion
Jason G. Miles, Nicholas A. Battista
Jellyfish - majestic, energy efficient, and one of the oldest species that inhabits the oceans. It is perhaps the second item, their efficiency, that has captivated scientists for…
Don't be jelly: Exploring effective jellyfish locomotion
Jason G. Miles, Nicholas A. Battista
Jellyfish have been called one of the most energy-efficient animals in the world due to the ease in which they move through their fluid environment, by product of their morphologic…
Fluid-Structure Interaction for the Classroom: Speed, Accuracy, Convergence, and Jellyfish!
Nicholas A. Battista, Matthew S. Mizuhara
When is good, good enough? This question lingers in approximation theory and numerical methods as a competition between accuracy and practicality. Numerical Analysis is traditional…
Fluid-Structure Interaction for the Classroom: Interpolation, Hearts, and Swimming!
Nicholas A. Battista
While students may find spline interpolation quite digestible, based on their familiarity with continuity of a function and its derivatives, some of its inherent value may be misse…
Modeling the prescription opioid epidemic
Nicholas A. Battista, Leigh B. Pearcy, W. Christopher Strickland
Opioid addiction has become a global epidemic and a national health crisis in recent years, with the number of opioid overdose fatalities steadily increasing since the 1990s. In co…
Under the sea: Pulsing corals in ambient flow
Nicholas A. Battista, Julia E. Samson, Shilpa Khatri +1
While many organisms filter feed and exchange heat or nutrients in flow, few benthic organisms also actively pulse to enhance feeding and exchange. One example is the pulsing soft…
Bifurcations in valveless pumping techniques from a coupled fluid-structure-electrophysiology model in heart development
Nicholas A. Battista, Laura A. Miller
We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a fluid-structure interaction framework based on the immer…
Three-dimensional low Reynolds number flows near biological filtering and protective layers
W. Christopher Strickland, Laura A. Miller, Arvind Santhanakrishnan +3
Mesoscale filtering and protective layers are replete throughout the natural world. Within the body, arrays of extracellular proteins, microvilli, and cilia can act as both protect…
Pulsing corals: A story of scale and mixing
Julia E. Samson, Nicholas A. Battista, Shilpa Khatri +1
Effective methods of fluid transport vary across scale. A commonly used dimensionless number for quantifying the effective scale of fluid transport is the Reynolds number, Re, whic…
IB2d Reloaded: a more powerful Python and MATLAB implementation of the immersed boundary method
Nicholas Battista, Christopher Strickland, Aaron Barrett +1
The immersed boundary method (IB) is an elegant way to fully couple the motion of a fluid and deformations of an immersed elastic structure. In that vein, the IB2d software allows…
IB2d: a Python and MATLAB implementation of the immersed boundary method
Nicholas A. Battista, W. Christopher Strickland, Laura A. Miller
The development of fluid-structure interaction (FSI) software involves trade-offs between ease of use, generality, performance, and cost. Typically there are large learning curves…
Fluid Dynamics in Heart Development: Effects of Hematocrit and Trabeculation
Nicholas A. Battista, Andrea N. Lane, Jiandong Liu +1
Recent \emph{in vivo} experiments have illustrated the importance of understanding the hemodynamics of heart morphogenesis. In particular, ventricular trabeculation is governed by…
On the dynamic suction pumping of blood cells in tubular hearts
Nicholas A. Battista, Andrea N. Lane, Laura A. Miller
Around the third week after gestation in embryonic development, the human heart consists only of a valvless tube, unlike a fully developed adult heart, which is multi-chambered. At…
Vortex dynamics in trabeculated embryonic ventricles
Nicholas A. Battista, Dylan R. Douglas, Andrea N. Lane +3
Proper heart morphogenesis requires a delicate balance between hemodynamic forces, myocardial activity, morphogen gradients, and epigenetic signaling, all of which are coupled with…
A comparison of heroin epidemic models
Nicholas A. Battista
The use of illicit drugs has been on the rise in United States. It is very detrimental on society, as fatal overdose is the fourth leading cause of death in the United States, whic…
Time evolution of a non-singular primordial black hole
Manasse R. Mbonye, Nicholas Battista, Benjamin Farr
There is growing notion that black holes may not contain curvature singularities (and that indeed nature in general may abhor such spacetime defects). This notion could have implic…
