This paper presents a three-dimensional ice accretion tool for rime and glaze ice types, developed based on foam-extend 5.0, in a new solver for icing applications: iceAccretionFoam. The purpose of this paper is to analyse the hydrodynamics of water films using the finite-area method, rough turbulent heat transfer modelling, the immersed boundary method to change the geometry, flow-ice shape interaction, impingement by Eulerian formulation and external flow solutions with the compressible solver rhoPimpleFoam. The work develops and implements a unified computational fluid dynamics (CFD) tool that is capable of modelling the entire process in one three-dimensional solver. The present work describes the second part of the initial development of a CFD tool, focusing on the water film hydrodynamic modelling, turbulent rough heat transfer, compressible flow unsteady solver and ice growth with a model based on a liquid-water film height time derivative that is applied for both rime and glaze types. The implementation was accurate and yielded acceptable initial results, as indicated by preliminary verification carried out by the authors.
