Investigation of deposition in aviation gas turbine fuel nozzles by coupling of experimental data and heat transfer calculations

► Fuel deposits were generated experimentally and modelled by heat transfer model. ► Results showed that deposition is largerly dependent on fuel inlet temperature. ► Heated tube initial wall temperature had a lesser effect on deposit formation. ► Uncertainty analysis demonstrated the reliability of the heat transfer calculations. ► The heat transfer model was found sensitive to thermocouple measurement accuracy.
