| Abstract: | The ice accretions have been predicted using the neural net method.A curvature coordinates was established to change the ice accretion shape into a geometrical curve through coordinates transformation.The Fourierseries was employed to fit the curve so as to parameterize the ice shape.The neural nets were established throughregarding the icing conditions as inputs and the ice shape parameters as outputs.The ice accretions on a NACA0012 airfoil were predicted using the trained net.The comparison among the pre... |
