Analytical model for time-dependent chloride diffusion in circular section concrete
Shuili Shuiyun Gongcheng Xuebao, 2019 In order to overcome the shortcomings of the traditional analytical model of constant diffusion which can not consider the time-varying characteristics of chloride diffusion coefficient, a time-dependent analytical model for the chloride diffusion in ...

Instability Induced by Cross-Diffusion in a Predator-Prey Model with Sex Structure
Journal of Applied Mathematics, 2012 In this paper, we consider a cross-diffusion predator-prey model with sex structure. We prove that cross-diffusion can destabilize a uniform positive equilibrium which is stable for the ODE system and for the weakly coupled reaction-diffusion system.

The spatial dynamics of a zebrafish model with cross-diffusions
Mathematical Biosciences and Engineering, 2017 This paper investigates the spatial dynamics of a zebrafish model with cross-diffusions. Sufficient conditions for Hopf bifurcation and Turing bifurcation are obtained by analyzing the associated characteristic equation. In addition, we deduce amplitude equations based on multiple-scale analysis, and further by analyzing amplitude equations five ...

Segregation and Gap Formation in Cross-Diffusion Models
, 2019 In this paper we analyse a class of nonlinear cross-diffusion systems for two species with local repulsive interactions that exhibit a formal gradient flow structure with respect to the Wasserstein metric. We show that systems where the population pressure is given by a function of the total population are critical with respect to cross-diffusion ...

Cube-based diffusion algorithm [PDF]
, 2007 We study molecular diffusion in (linear) nanopores with different types of roughness in the so-called Knudsen regime. Knudsen diffusion represents the limiting case of molecular diffusion in pores, where mutual encounters of the molecules within the free

Induction of patterns through crowding in a cross-diffusion model
Results in Applied MathematicsIn this paper we focus on pattern formation in systems of interacting populations. We show that if one considers these populations to be “crowded” in a way that is defined below, then cross-diffusion terms appear naturally.
