THE MODELLING OF DYNAMICS OF FLUID FLOW REGIME CHANGE IN THE SHIP PIPELINE DURING THE TRAINING OF MARINE ENGINEERS

Abstract

Introduction. One of the many safety problems of maritime shipping is the incorrect assessment by crew members of the vessel of the speed and strength of physical phenomena that cause an emergency. No less significant are the problems of reliable operation of numerous ship pipelines. Aggressive influence of marine fuel varieties and turbulent fluid flow mode lead to destruction of pipe surfaces, wear and vibration of pipelines and valves. These factors justify the relevance of studies of physical processes in the field of molecular physics and mechanics of continuous environments. The purpose of the work is the development of the professional competencies of marine engineers by the modeling the dynamics of changes in the fluid flow regime in the ship pipeline using a system-structural approach and information technologies. Results. Structural and functional diagrams of the ship pipeline system have been developed. A step-by-step method for studying the movement of liquid in straight smooth cylindrical pipes has been developed. At the laboratory stand "HYDRAULICS, HYDRAULIC MACHINES AND HYDRAULIC DRIVES" cadets conducted an experiment, calculated and visualized the results. The graphic display of fluid flow mode change dynamics is obtained. Calculated values at which turbulent liquid flows can lead to the occurrence of the phenomenon of the hydrodynamic cavitation and the cavitation corrosion. Conclusions. The work uses an integrated approach to the study of the educational component "Physics," which combines the knowledge and skills in the field of physics, the research methodology, and information technologies. The involvement of cadets in scientific and research work made it possible to develop the following competencies: practical skills in the classification of entities, skills in working with laboratory equipment, the ability to use analytical and experimental methods to solve complex problems, and information technologies for data processing, the ability to analyze information, formulate and substantiate the conclusions of the study.
