“…The flame extinction experiment selected for the first MaCFP workshop is a canonical line-fire configuration with controlled co-flow studied at the University of Maryland (UMD) [15–17]. The UMD turbulent line burner facility allows the study of a buoyancy-driven, turbulent diffusion flame exposed to environments of decreasing oxygen strength, down to the oxygen extinction limit, and thereby provides fundamental information relevant to fire suppression due to under-ventilation or due to the activation of an inert gas system.…”

This paper provides a report of the discussions held at the first workshop on Measurement and Computation of Fire Phenomena (MaCFP) on June 10–11 2017. The first MaCFP work-shop was both a technical meeting for the gas phase subgroup and a planning meeting for the condensed phase subgroup. The gas phase subgroup reported on a first suite of experimental- computational comparisons corresponding to an initial list of target experiments. The initial list of target experiments identifies a series of benchmark configurations with databases deemed suitable for validation of fire models based on a Computational Fluid Dynamics approach. The simulations presented at the first MaCFP workshop feature fine grid resolution at the millimeter- or centimeter- scale: these simulations allow an evaluation of the performance of fire models under high-resolution conditions in which the impact of numerical errors is reduced and many of the discrepancies between experimental data and computational results may be attributed to modeling errors. The experimental-computational comparisons are archived on the MaCFP repository [1]. Furthermore, the condensed phase subgroup presented a review of the main issues associated with measurements and modeling of pyrolysis phenomena. Overall, the first workshop provided an illustration of the potential of MaCFP in providing a response to the general need for greater levels of integration and coordination in fire research, and specifically to the particular needs of model validation.

Recently, water has been employed as a supportive agent for the preparation of multiple suppressing agents including aqueous film forming foams (AFFF), which is combined with different kinds of gases for its various applications. In this study, the water mist is chosen for the gas-suppressing agent such as carbon dioxide. Our work investigated the suppression effects of water droplets on the n-heptane pool fire, and its mixture with carbon dioxide, respectively. The size and frequency of droplets with their effect on temperature and suppression was compared to observe the difference in the suppression. Initially, it was found that the droplets having a larger droplet size were found to be more efficient as compared to the smaller droplets with respect to the heat release rate, temperature, and radiation. Afterwards, a mixture of water droplets and carbon dioxide was simultaneously discharged to compare the difference between these two suppressing agents. It was found that the synergistic effect of the mixture has higher advantages over the use of only water suppression. It helps reduce the hot gases that surround the pool fire and allows the water mist to travel efficiently towards the fuel. Both suppression mechanisms were set to similar initial parameters that lead to different outcomes.

The solution of the problem of developing approaches to the management of the emergency prevention process in the conditions of limited energy supply of emergency response measures is considered. Within the framework of solving the problem, the process of emergency management in the conditions of limited energy supply is analyzed and the scheme of managerial influence on the process of spreading the emergency situation in the conditions of limited energy supply is developed. A structural and logical model of emergency management in conditions of limited energy supply has been developed. Developed a structural and logical model of emergency management in conditions of limited energy supply, which consists of twelve units. These are monitoring of the situation, identification of risks, notification and evacuation of people, search and identification of the danger of emergence and spread of emergency in conditions of limited energy supply, decision-making on the use of special equipment for electricity generation, preparatory measures, information control measures. measures in case of spread of danger, localization of sources of spread of danger, decision-making on recovery without quarantine regime in the region of hostilities, impact on the situation, analysis of the effectiveness of preventive measures and emergency prevention measures. The location of the units on six hierarchical levels, connected by logical connections, provides information on the state of the region in conditions of limited energy supply through the elements of the monitoring system and impact on the region through the system of performers, providing a continuous management process to minimize the consequences of emergency. The obtained results allow, using innovative information and technical methods of emergency prevention of such nature, to further form a modern method of emergency response in conditions of limited energy supply of emergency response measures, supplementing the above methods with an effective crisis management system. Key words: emergency situation, structural-logical model, conditions of limited energy supply.
