Abstract The air ventilation system is one of the supporting systems in the machinery of a warship. High temperatures in the engine room can lead to an unpleasant atmosphere and, in particular, to heat stress for the operating personnel. This heat stress was caused by the design of the engine room ventilation system not meeting the requirements due to the supply and exhaust fan. Under the given conditions, the air temperature reached 50 °C, higher than the standard 45 °C. Therefore, it was necessary to conduct a thermal analysis and redesign the ventilation system using a 3D CFD (Computational

Ship indoor environments are related with comfort conditions and health risk problems. As a consequence, to obtain an adequate heating, ventilation, and air conditioning (HVAC) system, a redesign of the engine control room must be made. To answer this problem, an analysis of real thermal comfort conditions was carried out and a new air conditioning procedure is proposed. From the obtained results it can be concluded that comfort conditions in the bridge and dining room are close to neutral, while the most extreme conditions have been found in the engine room.

Ammonia is emerging as a promising zero-carbon marine fuel due to its high hydrogen density, low storage pressure, and long-term stability, making it well-suited for supporting sustainable maritime energy systems. However, its adoption introduces serious safety challenges, as its toxic, flammable, and corrosive properties pose greater risks than many other alternative fuels, necessitating rigorous risk assessment and safety management. This study presents a comprehensive investigation of potential ammonia leakage scenarios that may arise during the fuel gas supply process within confined compa

Ship structures may collapse or be severely deformed during a fire. To precisely assess the post-fire structural integrity of ships, in this study, a thermal–mechanical coupling data interface was created, employing a significant eddy simulation algorithm for fire dynamics and a technique to analyze the structural thermal–mechanical coupling reaction. PyroSim was utilized to build a fire scenario, exporting 3D data through the device’s own program, and then the ANSYS thermal–mechanical coupling model was employed to study the spatial temperature distribution under fire-induced conditions.

Natural ventilation can play a significant role, which requires careful evaluation. It is necessary to adopt numerical calculation methods to study the ventilation circuit. This paper illustrates a numerical study of an underground gypsum quarry in Italy using the Ventsim computer program. Through this study, it was possible to determine the improvement interventions necessary to optimize the airflow that reaches the active sites of the mine, avoiding the risk of air recirculation in the deepest zones.

The air tightness of buildings has the greatest potential for energy savings. Reduced fresh air intake raises concerns about natural ventilation systems and the need to provide users with a comfortable indoor climate. The pace at which heat is expelled from a building's interior surfaces increases with vent size, putting residents' health at risk and causing discomfort. The study aimed to evaluate critical factors that contribute to poor natural ventilation in residential buildings, and its associated effects.

Abstract. Natural ventilation as part of a greenhouse environment control system can save energy, reduce pollution, and cut the costs of production. Many studies have used the energy balance method to model greenhouse environments and calculate the rates of ventilation needed to control them. However, the efficacy of this method is influenced by many factors. There are often many parameters in the energy balance model, related to the greenhouse structure, crop growth, and climate. Thus, the effectiveness and applicability of greenhouse ventilation systems based on energy balance can be comprom

The ultimate aim of sustainability in buildings gained an additional new dimension as the start of the year 2020 saw a rapid worldwide spread of the infectious disease caused by a coronavirus named COVID-19. There is evidence that, in addition to person to person contact, the disease transmission occurs through airborne droplets/aerosols generated by breathing, speaking, coughing or sneezing. For that reason, building heating, ventilating and air conditioning systems can play an important role, as they may both contribute as well as reduce the transmission risk.
