Void fraction increase along boiling flows in heated vertical channels may be predicted fairly well from various one-dimensional correlations. However, these predictions do not provide information about the evolution of interfacial area concentration, which is one of the dominant parameters of dispersed gas-liquid flow and depends on the interface structure. In this paper, a three-dimensional Lagrangian simulation of saturated nucleate boiling in a uniformly heated vertical channel is proposed. Vapor is distributed in liquid in the form of discrete bubbles, and liquid-vapor mixture quality increases along the flow through bubble evaporation and additional nucleation.
