Abstract
The paper presents numerical simulation of two-phase flow in a heated
capillary with evaporation on the meniscus. To solve the problem, a model
of evaporation from meniscus was developed in which the dynamics of
liquid-vapour interface is described by the Cahn-Hilliard equation. The
numerical simulations were performed using commercial software for 2D
axially symmetric case. The flow evolution was analysed for different
values of heat transfer coefficient at the capillary wall and inlet liquid
mass flow rate.
