ING2309 Thermodynamics and Heat Transfer
The course will provide knowledge in thermodynamics and thermology for use in other technical specialisation courses. The cadets will be given the education necessary to handle operating and maintenance issues within areas of marine engineering and engine technology. After graduation, the cadet is able to communicate with others about thermodynamics and heat transfer both verbally, in writing and with a system of formulas. The cadet also has understanding of how new knowledge and methods in the area are developed, and what significance this has for the engineering practice. The course will provide a good basis for further studies.
The course plan follows the STCW code table: A-III/2 and the STCW function: Marine engineering at the management level.
The course covers the following academic content: Basic concepts and properties of fluids: density, pressure, temperature, compressibility, vapour pressure, mass flow and volume flow. State principles and equations of state properties for liquids and gases, relevant tables and charts (e.g. pV, Ts, hs, ph). Energy forms, work, heat, inner energy and enthalpy. The first law of thermodynamics, conservation laws for mass and energy. The 2nd law of thermodynamics, entropy and irreversibility, open and closed systems. Ideal circular processes for power generation and cooling, including the Carnot, Otto, Diesel, Dual, Rankine/Brayton and Stirling processes. Ship steam plants, components and fluid conditions in the plant. Dimensioning of compressed air tank for required volume and pressure with respect to desired mass flow. Humid air: characteristics, diagrams, equilibrium calculations, air conditioning systems. Heat transfer mechanisms: conduction, radiation, convection, dimensioning of heat exchangers, components and system integration.
The course is planned to be given by a civilian university.
