Calculation of the Indicators of the Risk of People Damage Considering the Variability of Their Presence in the Areas of Emergency Processes Impact at Hazardous Production Facilities
(2022) Sofyin, A. S.; Sumskoy, S. I.; Сумской, Сергей Иванович
Risk indicators, as a rule, are integral values for certain recipients (people, equipment, buildings, and structures) considering the frequency and degree of their damage as the result of exposure to hazardous factors of possible accidents with the release of hazardous substances. Risk indicators are used for assessing the efficiency of the compensatory measures, new industrial and fire safety requirements, or the risk of deviations from them when developing special technical conditions, safety case for hazardous production facilities. The list of the main calculated risk indicators was formed back in the 1970s–1980s. For example, in the domestic and foreign practice, the following indicators of the risk of people death are used: potential risk (individual risk), collective risk (average rate of death), social risk (societal risk), individual risk (there is no foreign analogue). Overview of the approaches to the calculation of these indicators is given in the article, it is shown that they are generally accepted. A new approach to the calculation of risk indicators is proposed, which allows to consider the location of people and the time of their stay in more detail. Consider, in particular, dynamics of changes in the number of people at the facility, and in its vicinity during a given period, and the likelihood of people being in different places of the potential hazard zone at a particular point in time. These innovations make it possible to consider, for example, presence of the employees in different places during the working day, temporary gatherings of people during the day, for example, at the lunchtime in the canteen. Example of performing calculations according to the presented methodology is given. Consistency of the obtained results is shown. © 2022, STC Industrial Safety CJSC. All rights reserved.

Recording of the cavitation phenomena when modeling flows in the trunk pipelines
(2020) Sverchkov, A. M.; Sumskoy, S. I.; Сумской, Сергей Иванович
© 2020, STC Industrial Safety CJSC. All rights reserved.In the article, it is proposed to use a numerical method based on the approach of S.K. Godunov to simulate boiling in a pipeline. The paper presents a statement of the real problem of modeling a water hammer, considering possible boiling of the transpor-ted liquid on a real object — an oil pipeline. When solving the problem, two variants of flow modeling when closing the valve installed at the end of the pipeline were carried out. In the first case, the possibility of liquid boiling was not considered. In the second case, this opportunity was considered. The performed numerical simulation showed that in the pipeline in emergency situations, liquid columns can be formed, sepa-rated by the cavitation zones and oscillating in different phases, respectively, at the collapse of the cavitation zones, which serve as a kind of pressure dampers, the collisions of liquid columns occur, which can lead, depending on the ratio of velocities, to hydraulic shocks that occur not on the valves, but on the linear part of the pipeline (local hydraulic shocks). The waves from these collapses, interacting with each other, create the new pressure peaks that do not coincide with the pattern of simple wave circulation, which are predicted in the simulations that do not consider possible liquid boiling. As a result, the pressures reached in the pipeline during fluid hammer is significantly different from what it would be in the absence of boiling. When boiling is considered, the maximum reached pressures are 40 % higher. Moreover, this excess is repe-ated. The detailed analysis of the pressure profile in the pipeline is given in the article. Based on the results of solving this prob-lem, it is concluded that when modeling pre–emergency and emergency situations in the pipeline, it is necessary to consider the process of possible liquid boiling, since sometimes, as in the presented case, the values of the pressure surges can be higher than the values of the pressure surges in the liquid without considering boiling, which increases the likelihood of emergency depressurization.
