ICON gets involved in Icing simulation. The example shown here depicts air accumulation in air generation systems.

The impact of accumulated ice on performance (added weight, pressure loss, etc.) and safety (structural damage, exceeded load limits, etc.) is non-negligible for aircraft air generation systems. A bespoke simulation methodology has been developed to predict the accumulation and effects of ice in internal 3D air flows. Features of this method include:

  • Prediction of ice build-up for realistic timeframes (several hours)

  • Prediction of first ice locations

  • Prediction of critical icing areas

  • Direct computation of accumulated mass of ice

  • Calculation of pressure loss due to ice build-up
