Dynamics of harmful factors in inclined road tunnels according to the results of numerical modeling of up to 50 MW fires in terms of natural ventilation

Autor: Lanchava Omar, Ilias Nicolae, Radu Sorin Mihai, Nozadze Giorgi, Javakhishvili Giorgi

Publikováno v: MATEC Web of Conferences, Vol 389, p 00056 (2024)

The present paper explores the change of the harmful factors by means of full-scale numerical models. In the numerical models, the tunnel length is 400 m; the slope gradient varies within 0-9%, with a 2% step; and the heat release rate is within 5-50

All main and auxiliary equipment in the tunnel with an intelligent ventilation system are designed to ensure the safety. These systems “talk” and “listen” to each other, make decisions to switch on/off certain system(s) or part(s) thereof and

Study of propagation of harmful factors of fire in short road tunnels with different inclinations

Autor: Ilias Nicolae, Lanchava Omar, Nozadze Giorgi, Tsanava David

Publikováno v: MATEC Web of Conferences, Vol 342, p 03023 (2021)

The paper considers the spread of combustion products caused by fires with different heat release rates: 5, 10, 15, 20, 30, 50 MW in up to 400 m long tunnels. The slope of the tunnels on numerical models is - 0, 1, 3, 5, 7, 9%. The cross-sectional ar

Numerical simulation of air flow in short metro ventilation shafts caused by a piston effect

Autor: Ilias Nicolae, Lanchava Omar, Nozadze Giorgi

Publikováno v: MATEC Web of Conferences, Vol 305, p 00050 (2020)

Protecting the infrastructure of the metro from unauthorized actions with the help of ventilation openings of the systems is one of the main security problems of this type of transport. This article discusses the problem of the dynamics of distributi
