Abstract
The article is aimed to the development of measures to reduce losses of bulk cargo due to blow-out during its transportation by open-top cars. The characteristics of the model range of open-top cars in use are analyzed, and the most important ones for organizing the selection of rolling stock, which affect the degree of filling of the body with cargo, are determined. The characteristics of bulk cargo that influence on the loading height into an opentop car are analyzed, and the most significant ones are identified, which determine both the degree of filling of the car body and the configuration of the cargo surface.
An aerodynamic model of the process of blowing out bulk cargo during transportation in open-top cars has been developed using specialized software in the field of Computational fluid dynamics (CFD). Based on the results of the model study, an algorithm has been developed for selecting optimal options for combining the characteristics of open-top cars used for transportation and specific brands and fractions of bulk cargo, which ensures minimization of cargo losses from blowing out.
