At present time, research in the field of chaotic systems is great interest. In particular, this is due to the need to find chaotic attractors, many of which have practical applications [1].

At the same time, it seems relevant to use p-adic analysis to study nonlinear dynamical systems. As showed result, which obtained in [2–4], this approach is presented as quite effective. In the present work, this approach is used to simulate the processes of phase transitions of the “liquid-gas” type. Molecular structures of phases are modeled by a node – communication system. In particular, it can be a Cayley tree with a root at the phase boundary. To analyze the p-adic model, use the Hamiltonian model:

$H=H_{v}+H_{g}$ (1)

$H_{v} \left ( \sigma \right ) =J_{v} \sum _{(x,y)\in L_{v}}\delta _{\sigma (x_{v})\sigma (y_{v}),} H_{g}(\sigma )=J_{g} \sum _{(x,y)\in L_{g}}\delta _{\sigma (x_{g})\sigma (y_{g})},$ (2)

Index $v$ refers to the liquid phase, index $g$ refers to the gas phase, $J_{v}$ $J_{g}$ are the coupling constants, $\delta _{ij}$ - the Kronecker delta, $L_{v},L_{g}$ characterize the geometry of the sets.

It is shown that the Gibbs energy can change abruptly from a limited value to infinity, which indicates the possibility of a phase transition and, accordingly, the breaking of bonds.
