Abstract
Aim. The purpose of the paper is to systematize the results of theoretical and experimental studies on the flow of a gas suspension around a blunt body, including supercooled drops.
Methodology. Computer modeling methods and experimental data are used in numerical calculations.
Results. A classification of regimes of a flow around a blunt body by a gas suspension flow is presented. The results of applying various research methods depending on the characteristic dimensions of the body, drops and the Knudsen number are systematized in the form of a diagram. A region is found in the flow around the leading edge of the wing, where supercooled drops will not crystallize upon hitting the surface.
Research implications. The results can be used in the modeling of icing and serve as a basis in the fight against this unfavorable phenomenon.
