Air Drag Controls the Finite-Time Singularity of Euler's Disk
Benjamin G. Thorne, Ahmad Zareei, Kausalya Mahadevan +2
The motion of a disk spinning to rest after being tipped on its side is a classic example of a finite-time singularity, yet the dominant dissipation mechanism governing this proces…
GNN-based physics solver for time-independent PDEs
Rini Jasmine Gladstone, Helia Rahmani, Vishvas Suryakumar +3
Physics-based deep learning frameworks have shown to be effective in accurately modeling the dynamics of complex physical systems with generalization capability across problem inpu…
Learning time-dependent PDE solver using Message Passing Graph Neural Networks
Pourya Pilva, Ahmad Zareei
One of the main challenges in solving time-dependent partial differential equations is to develop computationally efficient solvers that are accurate and stable. Here, we introduce…
Deep water wave cloaking using a multi-layered buoyant plate
Takahito Iida, Ahmad Zareei, Mohammad-Reza Alam
Trajectory of surface gravity waves in potential flow regime is affected by the gravitational acceleration, water density, and seabed depth. While the gravitational acceleration an…
Experimental Demonstration of Broadband Reconfigurable Mechanical Nonreciprocity
Amin Mehrvarz, Mohammad Javad Khodaei, Amir Darabi +2
Breaking reciprocity has recently gained significant attention due to its broad range of applications in engineering systems. Here, we introduce the first experimental demonstratio…
Temporal Evolution of Flow in Pore-Networks: From Homogenization to Instability
Ahmad Zareei, Deng Pan, Ariel Amir
We study the dynamics of flow-networks in porous media using a pore-network model. First, we consider a class of erosion dynamics assuming a constitutive law depending on flow rate…
Euler-Schrodinger Transformation
Ahmad Zareei
Here we present a transformation that maps the Schrodinger equation of quantum mechanics to the incompressible Euler equations of fluid mechanics. The transformation provides a wav…
Propulsion and Mixing Generated by the Digitized Gait of Caenorhabditis elegans
Ahmad Zareei, Mir Abbas Jalali, Mohsen Saadat +2
Nematodes have evolved to swim in highly viscous environments. Artificial mechanisms that mimic the locomotory functions of nematodes can be efficient viscous pumps. We experimenta…
Broadband Wall-less Waveguide for Shallow Water Waves
Ahmad Zareei, Mohammad-Reza Alam
We present a broadband waveguide for water waves obtained through mere manipulation of seabed properties and without any need for sidewalls. Specifically, we show that a viscoelast…
Broadband cloaking for flexural waves
Ahmad Zareei, Mohammad-Reza Alam
The governing equation for elastic waves in flexural plates is not form invariant, and hence designing a cloak for such waves faces a major challenge. Here, we present the design o…
Sensitivity of Internal Wave Energy Distribution over Seabed Corrugations to Adjacent Seabed Features
F. Karimpour, A. Zareei, M. -R. Alam
Here we show that the distribution of internal gravity waves energy over a patch of seabed corrugations strongly depends on the "distance" of the patch to adjacent seafloor feature…
Inherently Unstable Internal Gravity Waves due to Resonant Harmonic Generation
Y. Liang, Ahmad Zareei, M. -R. Alam
Here we show that there exist internal gravity waves that are inherently unstable, that is, they cannot exist in nature for a long time. The instability mechanism is a one-way (irr…
