Entropically damped artificial compressibility for the discretization corrected particle strength exchange method in incompressible fluid mechanics
Abhinav Singh, Ivo F. Sbalzarini, Anas Obeidat
We present a consistent mesh-free numerical scheme for solving the incompressible Navier-Stokes equations. Our method is based on entropically damped artificial compressibility for…
Spontaneous flow instabilities of active polar fluids in three dimensions
Abhinav Singh, Quentin Vagne, Frank Jülicher +1
Active polar fluids exhibit spontaneous flow when sufficient active stress is generated by internal molecular mechanisms. This is also referred to as an active Fréedericksz transit…
A meshfree collocation scheme for surface differential operators on point clouds
Abhinav Singh, Alejandra Foggia, Pietro Incardona +1
We present a meshfree collocation scheme to discretize intrinsic surface differential operators over scalar fields on smooth curved surfaces with given normal vectors and a non-int…
Limit Sets for Natural Extensions of Schelling's Segregation Model
Abhinav Singh, Dmitri Vainchtein, Howard Weiss
Thomas Schelling developed an influential demographic model that illustrated how, even with relatively mild assumptions on each individual's nearest neighbor preferences, an integr…
General Mechanisms for Inverted Biomass Pyramids in Ecosystems
Hao Wang, Wendy Morrison, Abhinav Singh +1
Although the existence of robust inverted biomass pyramids seem paradoxical, they have been observed in planktonic communities, and more recently, in pristine coral reefs. Understa…
Modeling Fish Biomass Structure at Near Pristine Coral Reefs and Degradation by Fishing
Abhinav Singh, Hao Wang, Wendy Morrison +1
Until recently, the only examples of inverted biomass pyramids have been in freshwater and marine planktonic communities. In 2002 and 2008 investigators documented inverted biomass…
