Abstract
†† The NASA ice accretion code LEWICE was used to simulate ice shapes generated from a bimodal large droplet icing cloud. An experimental effort was recently undertaken to simulate an icing cloud containing Super-cooled Large Droplets (SLD) in the Icing Research Tunnel (IRT) at the NASA Glenn Research Center. A spray sequencing method was used to reproduce the bimodal droplet distribution normally found in SLD clouds in nature. The numerical results are compared to ice shape tracings obtained from the experiments. Results indicate that agreement between code results and experiments is as good as or better than variations in the experiments resulting from differing methods for simulation of the natural icing cloud.
