A computational model of bleed air anti-icing and electrothermal de-icing have been added to the LEWICE 2.01 software by integrating the capabilities of two previous programs, ANTICE2 and LEWICE/ Thermal3. This combined model has been released as LEWICE version 2.2. This report presents the capabilities of the software package and provide results for both bleed air and electrothermal cases. A comprehensive validation effort has also been performed to compare the predictions to an existing electrothermal database. A quantitative comparison shows that for deicing cases, the average difference is 9.4°F (26%) compared to 3°F for the experimental data while for evaporative cases the average difference is 27°F (32%) compared to an experimental error of 4°F. An external review of its capabilities is also presented. This review reports a difference between 18% and 30% for the software when compared to an experiment on a production piccolo tube model.
