Sažetak
The analysis of complex probe geometry heating and cooling was done aiming to find the temperature distribution inside the probe versus time. An infrared thermography was used to measure surface temperatures while temperatures inside the probe were measured with thermocouples. The results obtained by means of the numerical model based on the control volume approach, where thermographic measurements were the input parameters, show good mutual accordance with the ones obtained by thermocouple measurement at referent points of the probe. The local and average heat transfer coefficients have also been calculated by means of a numerical model. Based on that data, it is possible to find the influence of heat transfer level on heating or cooling processes. The simulation of applied therodynamics problems, especially in heat treatment of metals, provides a possibility to predict and monitor temperature change for each single point inside the probe in a way which will guarantee that the desired microstructure is obtained. The goal of the project was to find a possibility to simulate similar processes without providing measurements for all possible setups of the furnace parameters, which will reduces costs and time.
