“…Hence, it is actually quite tough to find a transfer function of the output temperature change from the power input, because the temperature of the environment is time-dependent. Furthermore, as shown in work of Petras et al [59], the transient unit response of the heat solid system could be fractional order and as noted in Aoki et al [60] also, heat transfer coefficients may be fractional or non-integer order. Thus, the use of fractional order differential model may approximate well the time-dependent behavior of conductive systems of complex geometries with convective heat transfer.…”

“…Effectiveness of application of fractional-integral calculus is no longer open to doubt in many areas of science and technology. In the modern theory of heat and mass exchange, such a mathematical apparatus enables more accurate solutions for the physics of fractal media in comparison with the methods of integer integration [5][6][7]. For example, it was shown in [6] that dependence of temperature on time in a thermal system operating in the transient mode can be approximated and modeled by means of a differential equation of fractional order.…”

“…Likewise, the heat transfer process was modelled in [14] considering a part of the heat flux dispersed in the air around the material under study, whereas the authors of [7] analyzed heat conduction through a sphere. Additional modeling of thermal processes can be found, e.g., in [1], [2], [6], [9], [13].…”
