Critical behavior of the two dimensional 2A->3A, 4A->0 binary system

, 2004
The phase transitions of the recently introduced 2A -> 3A, 4A -> 0 reaction-diffusion model (G.Odor, PRE 69 036112 (2004)) are explored in two dimensions. This model exhibits site occupation restriction and explicit diffusion of isolated particles.

Reduced-Order Modeling of Diffusive Effects on the Dynamics of Bubbles [PDF]

, 2003
The Rayleigh-Plesset equation and its extensions have been used extensively to model spherical bubble dynamics, yet radial diffusion equations must be solved to correctly capture damping effects due to mass and thermal diffusion.
