The principal aim of this work is to elaborate a robust physical model and the corresponding numerical code for prediction of the icing startup due to numerous water nanoparticles in the supercooled humid air. For this purpose, a scientified approach was used which is based not on the quantum-mechanics considerations but on the information about intermolecular potentials (especially, Lennard-Jones (LJ), etc.) tightly connected with the state equations of the corresponding specie (e. g., van der Waals for air and water and Mie-Grünaisen for circumfluent body). u In other words, the principal idea of this work is to adequately ascribe certain macroscopic characteristics of a water nanoparticle which may significantly differ from those indicated in physical reference books for bulk materials.
