SECOND LAW ANALYSIS OF FILM COOLING
Second Law Analysis of Film Cooling
● Use of second law analysis to quantify aerodynamic and thermal energy losses.
● Consideration of a variety of film cooling configurations, and cambered vanes with and without film cooling.
● Quantification of temperature and pressure variations, as well as aerodynamic gains, using second law analysis.
● Also considered are interrelationships of entropy production and turbulence kinetic energy associated with simple angle and compound angle full coverage film cooling.
