A Graph Neural Network Simulation of Dispersed Systems
Aref Hashemi, Aliakbar Izadkhah
We present a Graph Neural Network (GNN) that accurately simulates a multidisperse suspension of interacting spherical particles. Our machine learning framework is built upon the re…
A multiple-timing analysis of temporal ratcheting
Aref Hashemi, Edward T. Gilman, Aditya S. Khair
We develop a two-timing perturbation analysis to investigate the existence of temporal ratchets in an exemplary system of a particle moving in a tank of fluid in response to an ext…
Computing hydrodynamic interactions in confined doubly-periodic geometries in linear time
Aref Hashemi, Raul P. Pelaez, Sachin Natesh +4
We develop a linearly-scaling variant of the Force Coupling Method [K. Yeo and M. R. Maxey, J. Fluid Mech. 649, 205-231 (2010)] for computing hydrodynamic interactions among partic…
Controlling the direction of steady electric fields in liquid using non-antiperiodic potentials
Aref Hashemi, Mehrdad Tahernia, William D. Ristenpart +1
When applying an oscillatory electric potential to an electrolyte solution, it is commonly assumed that the choice of which electrode is grounded or powered does not matter because…
Net motion induced by nonantiperiodic vibratory or electrophoretic excitations with zero time average
Aref Hashemi, Mehrdad Tahernia, Timothy C. Hui +2
It is well established that application of an oscillatory excitation with zero time-average but temporal asymmetry can yield net drift. To date this temporal symmetry breaking and…
