Refrigeración de gases de exhaustación en turbinas de gas marinas

Abstract

The purpose of this Doctoral Thesis is to study the feasibility of injecting water mist into the exhaust ducts of marine gas turbines, in order to reduce the temperature of the exhaust gases and, therefore, their contribution to the infrared signature of the vessel. Given the difficulty of carrying out experimental tests on ships, the use of Computational Fluid Dynamics techniques (CFD) has been chosen in order to predict the behaviour of the process of interaction of water mist and exhaust gases inside the ducts exhaust of the turbines. In this sense, CFD techniques will allow the planning and resolution of physicmathematical models to find approximate solutions to the equations that govern the phase interaction phenomenon.
