| Abstract: | A double film heat flux gauge is investigated theoretically and developed to measure heat flux on turbine blades or rotor stationary tip casing in turbine test facilities of short duration. The analysis shows that the heat flux is a function of the temperature histories on both sides of the gauge. It is also a function of two combined parameters which consist of thermal properties and size of the gauge. A method for calibration of the gauge is given. The design criteria and applied techniques of the gauge are described in detail. |
