Introducing the iceAccretionFoam solver: impingement and rime ice.

Abstract

This paper explores the capabilities of iceAccretionFoam, an innovative solver developed on top of the Foam-extend 5.0 code, for computing icing in two-dimensional domains, performed on a NACA0012 airfoil. The study presents droplet transport carried out by an incompressible unsteady Reynolds-averaged Navier-Stokes equation to determine Eulerian droplet flow. The results demonstrate the ability of the software to estimate pressure coefficient, collection efficiency and rime ice shape, indicating its potential use in icing simulations. Furthermore, the paper investigates the effect of different numerical schemes, linear solvers and turbulence models on the numerical results. The rime ice occurs only through accretion, excluding thermodynamic processes, accounting for ice growth effects with the immersed boundary method. The results exhibited consistency with the NASA experiments.This article is part of the theme issue 'Heat and mass transfer in frost and ice.'
