FENSAP-ICE has five modules
that form a complete, versatile, flexible in-flight icing
system:
-
FENSAP：a
3D finite element-based N-S solver
FENSAP solves the steady or
unsteady compressible 3D N-S equations. The fluid may be
inviscid or viscous, in which case the flow may be laminar
or turbulent, turbulence being modeled by one-equation or
two-equation models. It can assess the performance
degradation caused by ice build-up, based on calculating
parameters of the clean and contaminated
geometry.
-
OptiGrid：a 3D mesh adaptation and
CAD reconstruction tool
OptiGrid is a
comprehensive, automatic mesh adaptation and CAD
reconstruction software which helps achieve the most
accurate CFD simulations at the lowest computational cost.
It assesses the initial mesh's quality via a posteriori
error estimator, and generates anisotropic meshes to capture
complex phenomenon.
-
DROP3D：a 3D
finite element-based Eulerian droplets impingement
solver
DROP3D handles impingement for both external and internal flows. It
solves fine-grain partial differential equations for
droplets velocity and concentration. DROP3D thus provides,
in a single shot, catch efficiency distributions,
impingement patterns, shadowing characteristics and
impingement limits over the entire domain without the
laborious iterative procedure of seeding droplets at
injection points.
-
ICE3D：a 3D
finite volume ice accretion and water runback
solver
ICE3D is the 3D
ice accretion module of the FENSAP-ICE system, also based on
fine-grain partial differential equations for the complex
thermodynamics of ice formation. It yields 3D ice shape and
water film thickness on any number of complex 3D surfaces.
It can output the displaced 3D grid to compute performance
degradation due to ice accretion by simply restarting FENSAP
on this new grid.
-
CHT3D：a 3D Conjugate Heat
Transfer solver, including C3D for
heat conduction.
CHT3D is the 3D Conjugate Heat Transfer (CHT) module of the
FENSAP-ICE system which couples convection (from FENSAP) and
conduction (from C3D) for dry air heat transfer calculations
and, with DROP3D (droplets impact) and ICE3D (ice accretion)
for wet air anti-icing calculations. CHT3D is applicable to
a wide variety of other demanding complex fluid-solid
interface heat transfer situations.
