This paper discusses the extremisation of entropy production in fluidic networks to gain insight into using non-equilibrium thermodynamics for mathematically formulating thermal engineering transfer phenomena. In study, a variational formulation two-phase flow distribution junction is developed. Moreover, based on representation, it shown that distributed such rate either maximised or minimised. Specifically, considering homogeneous representation an adiabatic network, rates are maximize generation rate. Contrarily, when separate adopted, stationary yield minimum Additionally, various characteristics which affect ratio and phase separation, as geometric imbalance, gravitational static head, total inlet mass flux, different thermo-physical properties fluid, generalised number parallel branches explored. supports possibility relying thermodynamics, instead introducing case-specific empirical correlations, obtaining general mathematical formulations
