“…The authors of the article [12] summarized the experience of experimental works [13][14][15][16] in the field of using small-scale physical models for studying ascending smoke streams using the Froude number (Fr). We also analyzed our own experience obtained during commissioning tests of the smoke ventilation system of the multi-level underground park in Kazan, where hot smoke was also used [17][18][19] and Fr-based modelling was applied to reversible longitudinal jet ventilation systems [20][21].…”

“…A comparative analysis of the design rules for channel smoke ventilation of car parks built in Russia and Europe [5,6] was performed in this article [7]. It is shown that Russian regulatory documents allow lower performance of smoke exhaust fans, which can be a risk factor in modern multi-storey car parks with a ceiling height of 3.5 to 2.5 m [4].…”

Fire protection of closed car parks, where it is possible to have a massive stay of people, is the most important and most crucial task when designing such facilities. The efficiency and effectiveness of smoke ventilation systems is achieved through compliance with design rules and numerical simulation of air distribution. The most reliable method is an experimental check of the efficiency of smoke ventilation. It is not possible to reproduce a real fire in the conditions of an object without damaging the structures of a building or a facility; therefore, tests are carried out with reduced, safe fire parameters. Based on the similarity theory, the article discusses the methodology for scaling test fire parameters and smoke ventilation parameters, which allows obtaining results relevant to the design fire parameters. In this case, the positive test results with lower parameters of the test fire confirm the design limits of the smoke distribution and the possibility of evacuating people from the car park in case of a fire having design parameters. An alternative to these scaling methods can only be the prediction of design test parameters and conditions based on the same calculation method, as well as the case when the prediction of the test results is confirmed by observations.
