Computations of Pulsed Film-Cooling
Volume 4: Turbo Expo 2007, Parts A and B, 2007Direct Numerical Simulation (DNS) of a pulsed film cooling jet is presented to examine if pulsations of the coolant jet can enhance film cooling effectiveness. Calculations are performed for a cylindrical jet inclined at 30-degrees. The jet pulsation is defined by the duty cycle (DC) and the Strouhal number (St), both of which are varied in the present

Thermoelectric cool-film flow sensor
2012 IEEE Sensors, 2012Hemodynamics, specifically, fluid shear stress, plays an important role in the formation of arterial plaque known as atherosclerosis. For this application, hot-wire anemometers, being a robust and highly sensitive method for measuring flow properties, have a limitation in their sensitivity due to the effects of locally increasing temperature on nearby ...

Analysis of Film Cooling and Full-Coverage Film Cooling of Gas Turbine Blades
Journal of Engineering for Gas Turbines and Power, 1984Film cooling has become a standard method for the protection of the skin of gas turbine blades against the influence of the hot gas stream. The cooling air is usually injected into the boundary layer covering the skin through one or two rows of holes.
