Drop 3D

DROP3D is the 3-D Eulerian droplet impingement module of the FENSAP-ICE system. DROP3D piggybacks on existing CFD analyses (FENSAP, FLUENT, CFX or any other CFD code), and solves fine-grain partial differential equations to yield droplet velocity, water concentration, catch efficiency and shadowing limits over arbitrarily complex bodies (complete aircraft-turboprop and turbofans, helicopters, jet engines, UAVs, etc.).

For in-flight icing, DROP3D offers an on-screen access to the icing envelope of Appendix C to automatically select conditions of droplets size, liquid water content, altitude, temperature and cloud extent, and introduces their values to the solver, eliminating possible interpolation and transcription errors.

DROP3D also handles spatially-varying droplet sizes and liquid water content, at any inlet or in mid-field. This feature allows an improved simulation of internal components, of combined internal/external geometries such as air induction systems, and of the non-uniformities of in-flight testing or icing tunnels.

DROP3D can also be used for a wide variety of other situations where particles are suspended in a carrier fluid, including pollutant dispersal, fogging and soiling of automobile windshields, vapor deposition on computer chips, among others.
