“…It has been previously found that the leading suppression mechanism of a water mist system is the O 2 displacement that comes from a smaller droplet size, achieved with a higher operating nozzle pressure. Equation (4) shows that the pressure and discharge coefficient are inversely proportional; the spray momentum provides a K-factor for any given nozzle, highlighting the importance of nozzle selection when designing a water mist system.…”

“…The economic issues resulting from complex design and system components have been mentioned in different studies [4,44,77]. There are multiple methods of generating water mist, though they each come with expenses that can make water mist a costly option [77] when compared with alternative suppression methods, such as standard sprinklers or gaseous systems [44].…”

“…However, despite all efforts to substitute with alternative clean agents, the goal remains challenging due to several constraints. For example, using CO 2 to control fire can displace oxygen in the air and may be hazardous to human health [4]. Sprinklers are the most widely utilised fire suppression system in many applications, such as buildings, owing to their demonstrated efficacy in minimising the intensity of fire and fire spread beyond the fire origin.…”

Interest in water mist fire suppression has increased within the fire protection industry due to its ability to control the spread and development of fire without using environmentally damaging agents. Water mist fire suppression has been used for many years in various applications such as machinery spaces, combustion turbine enclosures, and onboard passenger sea vessels. Now there is a demand to use this firefighting method to protect other fire risks such as cooking areas, commercial buildings, residential buildings, electrical equipment, road tunnels, bushfire (wildland fire) protection, and nuclear power generation facilities. To support this industry demand, this review covers the fundamentals of water mist, its suppression mechanisms, areas of application, existing research and development, and the codes and standards related to design. This comprehensive review provides a clear history of water mist suppression. It is able to identify the issues and challenges related to the technology to help pave the way for future research and development that will improve these systems to a level so that they are suitable for these new applications and meet the industry demand for nontoxic fire suppression systems.

“…Ships, as the transport means with the largest single load and the most types of goods, have always played an important role in international transport. However, with the development of maritime transportation, ship transportation accidents occur occasionally, which seriously limit the sustainable development of the ship transportation industry [1,2]. Ship fires are the biggest safety issue in the shipping industry.…”

To further study the smoke dispersion and the temperature distribution in ship engine room fires, the fire dynamics solver buoyantReactingFOAM in the software OpenFOAM-10 is used to conduct a numerical simulation study on a pool fire caused by fuel oil leakage in a ship engine room. The applicability of this solver in simulating ship-engine-room-scale fires is validated by comparing it with experimental data. The impact of the mechanical ventilation, fire area, and fire position on the smoke dispersion and the temperature distribution in the ship engine room during the fire are considered in the simulation study, with a focus on the control room and the escape exit. The simulation results of buoyantReactingFOAM agree well with the experimental data. The simulated results of the case study show that for both in the control room and near the escape exit, among the factors of fire position, fire area, and the ventilation situation, the fire position affects the temperature distribution and the smoke dispersion most heavily, followed by the fire area and then the ventilation situation, which has the least influence on them. But, compared to the control room, the influence degree of the ventilation air velocity in the escape exit is larger than that in the control room. With an increase in the fire area, the spread rate of high temperature and high smoke concentration increases. With an increase in the ventilation air velocity, the aggregation degree of smoke and temperature decreases, but its decreasing range is very small when the ventilation air velocity is larger than 2 m/s.

“…[4,5] Over the years, statistics of passenger ship accidents show that fires are still one of the most common accidents on passenger ships. [6,7] Nowadays, the passenger ship is exquisitely decorated, with a complex cabin layout and many combustibles. The environment of the passenger ship is relatively confined.…”

To explore fire hazards and provide real‐time path navigation services for passenger ships, this study proposes an improved artificial fish swarm algorithm (IAFSA) to give the optimal evacuation route for evacuees when a passenger ship is on fire. First, the PyroSim software is used to simulate the fire scene on the sixth deck of the passenger ship. Through which the real‐time temperature, carbon monoxide (CO) concentration, and visibility of each exit are obtained, and the spread speed of the fire hazard area is determined. Then, the artificial fish swarm algorithm is improved by using the dynamic Visual and step, and the optimal path planning for the evacuation of passenger ships is achieved. The Visualized Evacuation Guidance System (VEGS) is developed to provide the optimal route for evacuees on the passenger ship. Finally, VEGS is applied to the fire evacuation of passenger ships. The results show that VEGS can provide the optimal evacuation path for evacuees and avoid detours in fire hazard areas compared with other algorithms. Seventy‐five percent of the evacuees who used VEGS in the event of a passenger ship can escape in a time shortened by up to 40.8%.
