Abstract. The refrigeration industry has undergone significant changes in recent years. In the past, chlorofluorocarbons (CFCs), such as R12, were widely used in refrigeration, but were found to be harmful to the ozone layer and replaced with hydrochlorofluorocarbons (HCFCs), for example, R22. Recently, more environmentally friendly substances have been developed - hydrofluorocarbons (HFCs), including R404A, R507A and R407C. Currently, these HFCs are the most popular refrigerants for medium-temperature cooling (from minus 5 C to +5 C). Although most HFCs have zero ozone depletion potential (ODP), they still contribute significantly to global warming due to their high global warming potential (GWP). That is why now more and more attention is being paid to natural refrigerants, which are considered as a potential solution for the future. They have favorable environmental properties, such as zero ODP and low GWP compared to traditional CFCs and HCFCs substances [1]. Among the natural refrigerants that attract interest in the modern refrigeration industry, carbon dioxide (R744) and propane (R290) can be distinguished. Not only does it not destroy the ozone layer, but it also has a very low GWP. Propane is also a promising natural refrigerant, which has a low GWP and does not harm the environment.

In this article, a comparative analysis of the efficiency of supercritical cycles R744 for use in medium-temperature cooling was carried out. A comparison was made with one of the most common refrigerants at present - R404A, as well as with propane (R290), which has the greatest competitiveness among natural working substances. The purpose of the study was to determine the efficiency and identify the possibilities of increasing this indicator in supercritical systems with carbon dioxide.

Keywords: cold, carbon dioxide, efficiency, chlorofluorocarbons, hydrochlofluorocarbons, supercritical systems, ozone layer, global warming potential, industry, ecology

Abstract. The shape of fluid flow through a stationary mesh fabric is examined using computer-aided fluid flow interaction. Numerical tests are carried out by comparing measurements of the flow around a circular cylinder that makes up the mesh plates. It has been found that modeling a small part of the mesh plate is sufficient to reproduce a full-scale network. The article studies the influence of free-stream velocity, diameter and length of filaments on turbulence fields. Unique flow patterns are shown, the distribution of turbulent kinetic energies in the wake area behind the intersections of the cylinders, which is of decisive importance influencing the engineer’s decision when designing fishing gear.

Abstract. A significant part of the marine accidents is caused by wear, damage, and defects of the ship hull. In the world practice of operation of large-capacity ships breakages of propeller shafts, damage of side cladding, pipelines, fuel tanks, power plants and other facilities are systematically observed. Corrosion is one of the most important structural degradation of old ships that decreases strength of ship structures under all types of stresses during their life. At the same time, the hull degradation does not occur evenly, and it is not always possible to identify signs of metal fatigue, hidden defects, as well as other indicators of an implicit threat to the safety of the ship.

Keywords: corrosion, ship hull degradation, ship life

On availability of the marine ships accidents investigation data

Abstract. There is no doubt that it is very important to obtain information related to investigation of marine accidents. Fires, collisions and groundings take the main part in the worldwide statistics of accidents. A lot of accidents, one way or another, are caused by improper operation of the main and auxiliary engines, as well as boilers. The detailed analysis of such cases allows us to learn a lesson from what happened in order to prevent similar accidents in the future. The investigation has a very positive effect on the state of maritime safety. The most important task of such investigations is to identify the reasons that caused the incident. Thus, marine accidents investigation files with recommendations for their prevention in the future help the marine industry in the whole. If investigation of the actual circumstances of maritime accidents is delayed and performed inaccurately, the view ofthe maritime incident becomes obscured and vague. This kind of investigation does not benefit the development of maritime practice. The purpose of this work is to research the availability of information about marine accidents for its study, systematization and implementation in the educational process in order to prevent similar accidents in the future. The object of the study is the data on marine vessel accidents published by some structures authorized to investigate accidents. The criteria for selecting these structures are a large number of vessels operating under the flag of a given state, or a large water area as a zone of responsibility, or heavy traffic in the zone of responsibility.

Keywords: accident, incident, maritime safety, statistical analysis, human factor

Abstract. The degree of reliability of solving the problem of multimode optimization of low-consumption turbines is largely determined by the coincidence of the true and assumed kinetic energy losses in the impeller. The analysis of methods for calculating energy losses in supersonic working grids by various authors has shown that the dependencies presented in these works allow them to be used only in the design mode and do not take into account the influence of the thickness of the input edges on the losses in the impeller. The paper presents generalizing dependences of kinetic energy loss coefficients in supersonic working grids of low-flow turbines, in a wide range of changes in the determining geometric and operating parameters, the influence of periodic unsteadiness of the flow is taken into account. The empirical dependences presented in the paper constitute a mathematical model for determining the coefficient of kinetic energy loss in supersonic working grids. This model can be used in modeling variable modes and multi-mode optimization of low-flow turbines.

Keywords: low-consumption turbines, variable modes, kinetic energy loss coefficients, supersonic working grids
