A disc to air heat flux error and uncertainty analysis applied to a turbomachinery test rig design
Convective heat transfer knowledge is important to gas turbine engine designers; and used in simulations to determine surface temperature, stress and hence critical component life, including blades.
Guidelines reported here on uncertainties in heat transfer obtained from surface temperature measurements conclude a significant (i.e. 60%) uncertainty in heat flux can occur from a ±0.8?C uncertainty in temperature.
This resulted in more stringent calibration (to ±0.2?C) of thermocouples on new test rigs enhancing the quality of data provided to Rolls-Royce. Funded by Rolls-Royce PLC the work attracted interest from manufacturers engaged on the EU Framework 6 project MAGPI. Contact: Timothy Scanlon, Email: timothy.scanlon@rolls-royce.com, Tel:01332246131.
