A POINT OF VIEW ON THE THEORY OF OPEN CYCLE GAS TURBINES

In the context of the high interest on the concept of energy, engineering education has to adapt to the modern technical requirements. In this respect, marine engineering, as a part of engineering education is facing curricula changes. This paper deals with an attempt related with the improving of the teaching syllabus of the discipline called Thermodynamics / Part 1, included in the curricula of future marine engineers, enrolled in Constanta Maritime University (CMU). More exactly, it is about the theory of open cycles of gas turbines. The need of improving this theory came from the fact that in the last decades, this technology became more and more attractive for different industries. Maritime industry is one of these, where it is registered a high interest for thermal performance improving. Thus, if the classic theory of open cycles gas turbines was based on considering the working fluid to be a perfect gas, having constant specific heats, the new approach is discussing the case of irreversible cycle and specific heats of air and flue gas depending on temperatures. Results the need of a new hour allocation. This theoretical basis is allowing a more detailed thermal efficiency evaluation and assessment of specific fuel combustion.
