Abstract
A physico-mathematical model is proposed for assessing the effect of centrifugal force on the characteristic dimensions of needle-shaped ice formed as a result of the collision of a large supercooled drop with a sphere rotating in a coaxial air flow. The mass loss of droplets upon collision with the surface due to splashing is taken into account. The numerical implementation of the model makes it possible to study the effect of surface properties on the icing process and, in particular, to estimate the ice-free surface area due to centrifugal force.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
