Rotational dynamics of bottom-heavy rods in turbulence from experiments and numerical simulations
Linfeng Jiang, Cheng Wang, Shuang Liu +2
We successfully perform the three-dimensional tracking in a turbulent fluid flow of small asymmetrical particles that are neutrally-buoyant and bottom-heavy, i.e., they have a non-…
A parallel cut-cell algorithm for the free-boundary Grad-Shafranov problem
Shuang Liu, Qi Tang, Xian-Zhu Tang
A parallel cut-cell algorithm is described to solve the free-boundary problem of the Grad-Shafranov equation. The algorithm reformulates the free-boundary problem in an irregular b…
Multiple solutions of Kazdan-Warner equation on graphs in the negative case
Shuang Liu, Yunyan Yang
Let be a finite connected graph, and let be a function such that . We consider the following Kazdan-Warner equation on :\[Δu+…
Heat transfer enhancement in Rayleigh-Bénard convection using a single passive barrier
Shuang Liu, Sander G. Huisman
In this numerical study on Rayleigh-Bénard convection we seek to improve the heat transfer by passive means. To this end we introduce a single tilted conductive barrier centered in…
Construction of fixed points of asymptotically nonexpansive mappings in uniformly convex hyperbolic spaces
Andrei Sipos
Kohlenbach and Leustean have shown in 2010 that any asymptotically nonexpansive self-mapping of a bounded nonempty -hyperbolic space has a fixed point. In this paper, we adapt…
From Rayleigh-Bénard convection to porous-media convection: how porosity affects heat transfer and flow structure
Shuang Liu, Linfeng Jiang, Kai Leong Chong +6
We perform a numerical study of the heat transfer and flow structure of Rayleigh-Bénard (RB) convection in (in most cases regular) porous media, which are comprised of circular, so…
Selected topics on reaction-diffusion-advection models from spatial ecology
King-Yeung Lam, Shuang Liu, Yuan Lou
We discuss the effects of movement and spatial heterogeneity on population dynamics via reaction-diffusion-advection models, focusing on the persistence, competition, and evolution…
Asymptotics of the principal eigenvalue for a linear time-periodic parabolic operator II: Small diffusion
Shuang Liu, Yuan Lou, Rui Peng +1
We investigate the effect of small diffusion on the principal eigenvalues of linear time-periodic parabolic operators with zero Neumann boundary conditions in one dimensional space…
Asymptotics of the principal eigenvalue for a linear time-periodic parabolic operator I: Large advection
Shuang Liu, Yuan Lou, Rui Peng +1
We investigate the effects of advection on the principal eigenvalues of linear time-periodic parabolic operators with zero Neumann boundary conditions. Various asymptotic behaviors…
