Characteristic cooling times for these processes are calculated. It is found that the characteristic cooling time increases in the series of radiation, heat conduction, and convection, linearly depending on the ratio of the sample volume to its surface area. Using experimental data on the cooling rate of the samples and theoretically calculated values of heat capacity by the Neumann-Kopp rule, the heat transfer coefficients for the processes of convection, heat conduction, and radiation as a function of temperature are estimated. It was found that with increasing temperature, the coefficients of radiative and conductive heat transfer increase, while the convective heat transfer coefficient decreases. A comparison of the heat transfer coefficients shows that within the experimental error, they do not depend on the sample length.</p>}, number={2}, journal={Engineering Science & Technology}, author={Nizomov, Z. and Sodatdinov, S. and Saidzoda, R.
