摘要
The reconstruction of the distribution of the heat transfer coefficient ( HTC) for the air jet impinging of a solid object is discussed. After an optimal turbulence model is selected, computational fluid dynamics is used to obtain detailed information about the HTC produced by a jet and to validate its invariability in time. Two inverse models of the temperature field in the solid impinged by the jet are derived as a linear combination of known, constant, or linear auxiliary fields. Simultaneous minimization of the discrepancies between the temperatures measured by an infrared camera and both inverse models produces the distribution of the HTC for various jets configurations.
