“…The purpose of the engine room simulator (ERS), including actual ship features, is to make realistic analyses of the main engine and other systems in maritime training processes. ERS is also often preferred for examining and testing targeted situations used in academic studies (Rubio et al, 2018;Stavinuk et al, 2021). ERS was used for a fuel-water emulsion operating system to reduce exhaust gas emissions for a ship engine (Laskowski et al, 2015).…”

In recent years, ecological degradation has increased and drawn many environmental problems with it. One of the outcomes is the mucilage problem, which directly affects tourism, fishing, and especially the maritime sector. The recent mucilage outbreak in the Sea of Marmara has brought attention to these environmental disaster-related studies. However, there are only a few studies about mucilage’s effect on maritime transportation. In this context, the impact of mucilage on a marine vessel is examined within the scope of the study. One of the major negative effects of mucilage on a vessel is, its cooling system. Due to the mucosal formation of mucilage, it clogs the filters and reduces the cooling effect of seawater. In our paper, a case study was made, and data was obtained from a simulator. The seawater filter in front of the seawater pump was clogged by 0%, 30%, 45%, and 60% during the simulated case studies. 0% is the base condition that is not clogged by the mucilage while the other three cases are partially clogged. A comparison study was made according to the data gathered from the simulator. While the filter is clogged by 60% main engine is in slow down condition, but during 30% and 45% of cases, pumps tried to compensate cooling effect by increasing the seawater flow. However, enough cooling effects on the main engine jacket water, air cooler, lubrication oil cooler, steam condenser, and air compressor were not provided. Moreover, the reduced cooling effect increases fuel oil consumption which leads to higher CO2 emissions. These results show that mucilage not only affects fishing, and tourism but also affects the environment by increasing the fuel oil consumption of a vessel.

“…A heat flow meter is used for heat flow measurements on small curved surfaces. Stanivuk et al [13] proposed a method to predict the maximum temperature and time constant inside different power cabins. Hoang et al [14] quantitatively confirmed whether the cooling system could meet the requirements of the power drive unit for the cooling temperature to be lower than 65°C through unit tests and one-dimensional simulation.…”

New energy vehicles have better clean and environmental protection characteristics than traditional fuel vehicles. The new energy engine cooling technology is critical in the design of new energy vehicles. This paper used oneand three-way joint simulation methods to simulate the refrigeration system of new energy vehicles. Firstly, a k-ε turbulent flow model for the cooling pump flow field is established based on the principle of computational fluid dynamics. Then, the CFD commercial fluid analysis software FLUENT is used to simulate the flow field of the cooling pump under different inlet flow conditions. This paper proposes an optimization scheme for new energy vehicle engines' "boiling" phenomenon under high temperatures and long-time climbing conditions. The simulation results show that changing the radiator's structure and adjusting the thermostat's parameters can solve the problem of a "boiling pot." The optimized new energy vehicle engine can maintain a better operating temperature range. The algorithm model can reference each cryogenic system component hardware selection and control strategy in the new energy vehicle's engine.

Modern cooling systems for large ships are quite complex. As a rule, such systems are common (combined) for the main and auxiliaries engines. With the auxiliary engines running constantly, even when parked, this system design allows to keep it warm and ready for a quick start of the main engines at any time. Currently, various schemes of such systems are used, including those that are irrational from our point of view. At the same time, there are systems whose schemes are quite consistent with our idea of the rational forms of such structures. It is important to note, and it is saying about it in an article, that such schemes may have a number of significant differences, but at the same time they will comply with the rationality principle if certain rules for the formation of such systems are followed. These schemes will have close compactness. It is also important that there is the possibility of further improvement of such schemes based on certain rules. This improvement is possible due to the introduction of additional heat dissipaters and the organization of appropriate chains of heat sources and heat dissipaters. The article discusses various options for rational schemes of the cooling system for the same ship power plant, as well as the possibility of further improvement of this scheme. It is shown that an increase in the number of coolants of the internal circuit coolant from one to three can reduce the total mass of the heat exchanger cores by 18 %.
