Advancing the iceAccretionFoam Solver: Glaze Ice Accretion

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 analyze the hydrodynamics of water films using the finite area method, rough turbulent heat transfer modeling, 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 modeling the entire process in one 3D solver. The present work describes the second part of the initial development of a CFD tool, focusing on the water film hydrodynamic modeling, turbulent rough heat transfer, compressible flow unsteady solver, and ice growth with a model based on 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
