Abstract
This article analyzes the methods and models suitable for studying the icing of the aerodynamic surface (wing). Systems to counteract the unifying effect are considered. Methods and models for calculating ice formations on aerodynamic surfaces are studied. Further study of the effect of icing will be conducted in the light of the characteristics of flow around bodies of viscous compressible medium in terms of load and liquid phase in case of changes in the geometric parameters of the bodies and reflect this change in the external stream.
Highlights
It became possible to simulate the process of fouling the aerodynamic surface with frost, frost and ice
Icing occurs due to the presence of water droplets that are in a supercooled state, which get on the" cutting " edge of the continuous medium, freezes, gradually changing the shape of the streamlined surface, as a result of which the characteristics of the aerodynamic surface change
At the present stage of development of science, there are already mathematical models of aerodynamic profile icing in which the technique is reduced to the following stages: determining the geometry of the wing, searching for a potential solution for the flow, calculating the boundary layer, determining the trajectories of drops, the equation of the thermal balance of mass conservation and changes in the geometric shape after icing
Summary
To find solutions to complex problems fluid and gas mechanics became possible thanks to a leap in the development Computer and numerical methods, computational aerodynamics, which is why the possibilities of mathematical modeling have expanded. It became possible to simulate the process of fouling the aerodynamic surface with frost, frost and ice. Icing of the aerodynamic surfaces of machines and aggregates is a very dangerous effect, both for human safety and for the resource of mechanisms. At the present stage of development of science, there are already mathematical models of aerodynamic profile icing in which the technique is reduced to the following stages: determining the geometry of the wing, searching for a potential solution for the flow, calculating the boundary layer, determining the trajectories of drops, the equation of the thermal balance of mass conservation and changes in the geometric shape after icing. There are a number of undesirable effects, such as a decrease in the lifting force of the wing, an increase in the load on the elements, and a loss of efficiency. The ice crust can collapse under the influence of vibrations or aerodynamic forces, causing damage to the machine unit
