Development of a three-dimensional icing simulation code in the NSMB flow solver
Résumé
An icing model is developed in the NSMB (Navier-Stokes Multi-Block) compressible solver.The code implemented in this study is based on an Eulerian formulation for droplets tracking solved implicitly by means of CGSTAB or SIP methods, a modified iterative Messinger model using an improved water runback scheme for ice thickness calculation and three-dimensional mesh deformation to track the ice/air interface through time. The whole process is parallelized with MPI for complex multi-block configurations. The validated on several test cases including NACA23012 and NACA00012 airfoils and ONERA-M6 swept wing. Pressure coefficient around iced 23012 airfoil is compared with experimental data. Rime icing is computed on a DLR-F6 wing/body configuration. In all studied cases, the results are in good agreement with the literature.
