Computing effective diffusivity of chaotic and stochastic flows using structure preserving schemes
Zhongjian Wang, Jack Xin, Zhiwen Zhang
In this paper we study the problem of computing the effective diffusivity for a particle moving in chaotic and stochastic flows. In addition we numerically investigate the residual…

Residual Diffusivity in Elephant Random Walk Models with Stops
Jiancheng Lyu, Jack Xin, Yifeng Yu
We study the enhanced diffusivity in the so called elephant random walk model with stops (ERWS) by including symmetric random walk steps at small probability . At any , th…

Curvature effect in shear flow: slowdown of turbulent flame speeds with Markstein number
Jiancheng Lyu, Jack Xin, Yifeng Yu
It is well known in the combustion community that curvature effect in general slows down flame propagation speeds because it smooths out wrinkled flames. However, such a folklore h…
