On the thermal effect of porous material in porous media Rayleigh-Bénard convection
Jun Zhong, Shuang Liu, Chao Sun
We perform a two-dimensional numerical study on the thermal effect of porous media on global heat transport and flow structure in Rayleigh-Bénard (RB) convection, focusing on the r…

Global invariant manifolds delineating transition and escape dynamics in dissipative systems
Jun Zhong, Shane D. Ross
Invariant manifolds play an important role in organizing global dynamical behaviors. For example, it is found that in multi-well conservative systems where the potential energy wel…

Geometry of escape and transition dynamics in the presence of dissipative and gyroscopic forces in two degree of freedom systems
Jun Zhong, Shane D. Ross
Escape from a potential well can occur in different physical systems, such as capsize of ships, resonance transitions in celestial mechanics, and dynamic snap-through of arches and…
