Ansys FENSAP-ICE

Overview

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.

Features

• Supports Large-Scale Calculations on Multiple Platforms

FENSAP-ICE takes advantage of parallel architectures for large-scale calculations. The software is supported on Linux and Windows platforms.

• Saves Prep Time by Automatically Recalculating Iced Geometries

FENSAP-ICE performs automatic regridding of iced geometries for multiple accretion layers. This reduces manual setup time and increases ice shape accuracy, especially in glaze ice conditions. FENSAP-ICE also includes a rotating frame of reference for the analysis of turbomachines, rotors and propellers.

• Simulates Droplet Sizes

DROP3D, the droplet impingement module, simulates spatially varying droplet sizes and liquid water content at any inlet or in mid-field. It correctly models internal components, combined internal and external geometries such as air induction systems, and the non-uniformities encountered in natural flight and icing tunnel testing.

• Simulates Ice Growth and Performs Visibility Studies

ICE3D, the ice growth module, enables you to perform visibility studies for cockpits and car windshields in above-freezing temperatures, with runback. This feature also leads to enhanced ice growth accuracy on surfaces maintained above freezing by thermal ice protection systems.

• Models Heat Transfer Anti- and De-icing Heat Loads

CHT3D, the heat transfer module used for bleed air-ice protection or electro-thermal systems optimization, simulates multiple air–solid interfaces and multilayer conduction, with varying physical properties and phase changes. FENSAP-ICE is an ideal tool to analyze and optimize electro-thermal system stack-up; it models all layers — including dielectric, conductors and adhesive — and heater cycling to give accurate skin temperature distributions in wet air.

• Interfaces With a Most Common CFD Simulation Tools

Including ANSYS Fluent, ANSYS CFX, CGNS, STAR-CCM+, FINE/Turbo and others.
