Icing on intake screens can be used to calculate blockage effects. Mesh Optimization with OptiGrid One of the major difficulties of CFD is that computational meshes must be generated before the location and details of the solution can be known, an empirical process that requires user experience but invariably leads to less-than-ideal results. Freezing drizzle and freezing rain. Commercial aircraft cruise at altitudes where adverse meteorological phenomena such as icing clouds are rare and can generally be avoided. Ice build-up on wings, stabilizers and rotors is detrimental to the aerodynamic performance of these components. The airflow domains are separated from the metal or composite skin of the aircraft component;, therefore, all the ANSYS airflow solvers can be used. For bleed-air systems, a steady-state thermal equilibrium between domains is computed to verify that the protected region is free of ice.

FENSAP-ICE allows the user to define total water content and liquid water content, provides all the models to simulate the complex physics of crystal ice accretion and covers the entire ice crystal environment.

For electro-thermal systems, the IPS response time to the cyclic activation of heater pads is analyzed in a time-dependent CHT simulation encompassing phase change, heat conduction and water runback to accurately predict the amount of ice that forms, melts and refreezes.

Fensap-ive reduces lift, increases stall speed, reduces feensap-ice angle of attack, significantly increases drag which could be difficult to overcome for small aircraft, causes strong vibrations on helicopter rotors, increases the blockage between turbomachine compressor rotor blades, etc.

Icing on intake screens can be used to calculate blockage effects. A similar graphical environment is provided for Appendix D, also introduced in by the FAA to ensure protection against hard-to-detect ice crystals occurring at high altitudes over strong convective cells. Freezing drizzle and freezing rain.

OptiGrid is an anisotropic mesh optimization tool that is included to easily obtain high quality mesh- and user-independent results. SLDs have the potential to bypass ice protection systems designed to comply with Appendix C, and are therefore very dangerous. Commercial aircraft are therefore fitted with ice protection systems and must be certified to fejsap-ice safely in known icing conditions. Accidents do happen due to in-flight icing and unfortunately some of them have been fatal. Large glaze horns can be simulated in 2D and 3D with Multishot.

It has a built-in graphical interface to facilitate selection of icing conditions from Appendix C, D, and O. Results can then be used to assess the losses in performance of iced components.

One of the major difficulties of CFD is that computational meshes must be generated before the location and details of the solution can be known, an empirical process that requires user experience but invariably leads to less-than-ideal results. FENSAP-ICE provides leading three-dimensional, state-of-the-art, design and aid-to-certification simulation software to provide enhanced aerodynamic and in-flight icing protection solutions in a cost-effective manner by addressing all five major aspects of in-flight icing:.

OptiGrid provides solution-based anisotropic mesh optimization for high-precision CFD simulations on unstructured hybrid grids at the lowest possible computational cost. The first three operations accelerate the optimization, but only node movement ensures that the node locations, edge lengths, directions and aspect-ratio of the cells are truly optimized and meet the desired requirements.

Calculate the shapes and roughness distributions of glaze, rime or mixed-type ice accretion on aircraft surfaces ranging from wings to air data probes.

For bleed-air systems, a steady-state thermal equilibrium between domains is computed to verify that the protected region is free of ice. Recent studies have indicated that ice buildup can occur in the low-pressure compressor in mixed-phase environments, containing little or no droplets, but a large concentration of ice crystals.

OptiGrid removes this difficulty by estimating and then equi-distributing the truncation error of fendap-ice solution variables with four operations: Various roughness models are provided, including an analytical model that eliminates dependence on empirical correlations. Commercial aircraft cruise at altitudes where adverse meteorological phenomena such as icing clouds are rare and can generally be avoided.

Airflow; Droplet and ice crystal impingement; Ice accretion; Aerodynamic degradation; Anti- and de-icing heat loads. But during take-off and landing, they may not be able to avoid crossing atmospheric layers where adverse flight conditions may be encountered at the worst possible time: Mesh Optimization with OptiGrid One of the major difficulties of CFD is that computational meshes must be generated before the location and details of the solution can be known, an empirical process that requires user experience but invariably leads to less-than-ideal results.

Severe ice build-up on the suction side of fenaap-ice can lead to loss in aileron control, while ice on horizontal stabilizers can cause tail stall.

The accreting ice causes airflow distortion and blockage, resulting in compressor rollback and even surge. The benefits are superior accuracy on the most computationally-efficient meshes possible, and a mesh independence study every time cycles of solution and mesh optimization are performed.

Keywords for this software Anything in here will be replaced on browsers that support the canvas element.

A wide variety of IPS configurations can be analyzed. Many turbofan engine incidents characterized by flameout or rollback events in the presence of ice crystals at high altitudes have been reported by flight safety agencies.

FENSAP-ICE provides leading three-dimensional, state-of-the-art, design and aid-to-certification simulation software to provide enhanced aerodynamic fensa-pice in-flight icing protection solutions in a cost-effective manner by addressing all five major aspects of in-flight icing: Having no significant geometric limitations, it is applicable to aircraft, rotorcraft, UAVs, jet engines, nacelles, probes, detectors and other installed systems.

Ice build-up on wings, stabilizers and rotors is detrimental to the aerodynamic performance of these components. In-flight icing is a safety-critical aspect of aircraft design, yet it is a highly complex physical phenomenon that is extremely difficult to replicate using expensive physical tests. The ice shapes on wings, stabilizers, control surfaces, air data probes, rotors and propellers, turbofan blades and passages, radomes, cameras, etc.
