FENSAP-ICE applies state-of-the-art, 3-D Navier-Stokes, CFD-like models to in-flight icing. You can choose conditions using on-screen access to the icing envelope of Appendix C. Then FENSAP-ICE automatically determines and sends to the solver values for droplet size, liquid water content, altitude, temperature, and cloud extent to eliminate possible interpolation and transcription errors. As a result, you can accurately calculate the flow solution, droplet impingement, ice accretion, anti- and de-icing heat loads, and aerodynamic performance degradation.
