Icing Concepts

These concepts help users to perform icing simulations in ANSYS Fluent.

There are three main aspects of in-flight icing simulation. To achieve each of the three steps, simulations and calculations are performed sequentially in the three relevant solvers:

• Airflow

• Particles

• Ice Accretion

Airflow simulation is performed in ANSYS Fluent software at the Premium level to model the initial fluid flow before defining the icing process. Meanwhile, particles and ice calculations are performed in ANSYS Fluent software with the icing solver option at the Enterprise level to simulate the final icing process.

In particle simulation, the focus is on selecting the type of particles to prepare for the icing procedure. Types of particles required for icing include:

• Droplets

• Ice Crystals

• Vapor

In ice simulation, the focus is on selecting the physical model of ice to describe the ice accretion process. Types of required ice models include:

• Glaze

• Rime

• Water Film
