摘要

To study the thermophysical characteristics of plant tissues of fruits and root crops, flat samples of which can be obtained by mechanical cutting methods, a method of a flat pulsed heat source is proposed. A mathematical model of the heat transfer process in a measuring cell is developed, and an algorithm for processing experimental data on the change in temperature difference over time, recorded during the experiment, is proposed. It is proven that the use of the proposed algorithm for processing experimental data allows reducing the errors in measuring thermophysical characteristics.
