“…Therefore, CFD (computational fluid dynamics) is expected to provide a useful method by which to predict ice accretion phenomena, because of the rapid development of computers in recent years. Various icing simulations can be conducted through two-dimensional simulations using a NACA (National Advisory Committee for Aeronautics) airfoil for three-dimensional simulations of a jet engine [5][6][7][8].…”

Abstract:In the jet engine, icing phenomena occur primarily on the fan blades, the FEGVs (fan exit guide vanes), the splitter, and the low-pressure compressor. Accreted ice disturbs the inlet flow and causes large energy losses. In addition, ice accreted on a fan rotor can be shed from the blade surface due to centrifugal force and can damage compressor components. This phenomenon, which is typical in turbomachinery, is referred to as ice shedding. Although existing icing models can simulate ice growth, these models do not have the capability to reproduce ice shedding. In the present study, we develop an icing model that takes into account both ice growth and ice shedding. Furthermore, we have validated the proposed ice shedding model through the comparison of numerical results and experimental data, which include the flow rate loss due to ice growth and the flow rate recovery due to ice shedding. The simulation results for the time at which ice shedding occurred and what were obtained using the proposed ice shedding model were in good agreement with the experimental results.

Esentepe Mah. C ƒ evreyolu Blv., Tepebaƒ sŠ, Eskiƒ sehir 26003, TurkeyIce shape predictions for a NACA0012 airfoil and collection e©ciency predictions for the Twin Otter airfoil are obtained and presented. The results are validated with reference numerical and experimental data. Ice accretion modeling mainly consists of four steps: §ow ¦eld solution; droplet trajectory calculations; thermodynamic analyses; and ice accretion simulation with the Extended Messinger Model. The models are implemented in a FORTRAN code to perform icing analyses for twodimensional (2D) geometries. The results are in good agreement with experimental and numerical reference data. It is deduced that increasing computational layers in calculations improves the ice shape predictions. The results indicate that collection e©ciencies and impingement zone increase with increasing droplet diameter.
