Sycamore, thank you for the referenced report. In fact, all the test reports are much closer on the application, than my work will be. I'm rather looking onto the involved physics such as drop impact, nucleation and solidification; and finally their mutual interaction. Hence, a further step is still required from my work towards a potential improvement of numerical or theoretical icing codes...
"...but still very interested in the subject." Obviously... ;-)
Thanks again for your support and information!
