Abstract:Measurements using a novel heat flux sensor were performed in an internal ribbed channel representing the internal cooling passages of a gas turbine blade. These measurements allowed for the characterization of heat transfer turbulence levels and unsteadiness not previously available for internal cooling channels. In the study of heat transfer, often the fluctuations can be equally as important as the mean values for understanding the heat loads in a system. In this study comparisons are made between the time-… Show more
“…Heat fluxes in the range of _ q W ¼ 10 W=m 2 up to 20 kW/m 2 with frequencies of up to 1 MHz can be sampled. Detailed information on the measurement principle and the application of these sensors to transient heat transfer measurements can be found in Knauss et al (2002) and Jenkins et al (2008).…”
