Development of an experimental installation for modeling a single-circuit marine diesel cooling system

The material presented in this article is intended to solve the problem of using a single-loop cooling system for ship diesel engines installed on coastal vessels in areas of northern seas in our country. The proposed cooling system scheme suggests abandoning the external contour of ballast water, and heat removal from the coolant is carried out convectively into the surrounding air. Located in the location of the refrigerator will also help solve the problem of icing of the structural elements in the bow part of the ship, which will ensure safety during winter operation. An overview of the main technical characteristics of the power plant of the tug boat project 376 has been performed, as well as a consideration of the existing cooling system of this catamaran. Developed a setup that simulates a one-loop cooling system, allowing at an early stage of design to determine the geometric parameters of the tubing-cooler, which is provided as an apparatus for removing heat from the cooling liquid of the ship's diesel engine. Designated components and their functions are outlined, along with the methods used to determine the defining parameters of the developed setup. This installation can be used to simulate a one-loop cooling system of other types of ships, using appropriate parameters of the components of the setup. On the setup under development, it is proposed to conduct research under various conditions of the surrounding environment and using different types of cooling liquids that may differ in physical properties.
