Heat Transfer Problems in Advanced Gas Turbines for Naval Applications.
Abstract
The report covers heat exchanger studies stressing measurements of local heat transfer coefficients by a method based on the heat and mass transfer analogy. Local ablation rates are obtained on a model covered with napthalene and from these heat transfer rates are deduced through the analogy. Impingement cooling and porous wall heat transfer have also been investigated. A number of studies in film cooling were also completed: Experiments covered measurements in a cascade, effects of free stream conditions and of laminar boundary layer. A laser-Doppler setup was used to measure local and instantaneous velocities at the exit cross-section of a gas turbine combustor and turbulence intensities were derived. (Author)
