On the application of the thermal conductivity equation to describe the diffusion process

Abstract

The paper addresses the very popular issue of diffusion of innovations. Diffusion of innovations is the last stage of the innovation process and an indicator of its success. The study of the diffusion of innovations and the application of heat conduction equations in this theory is related to the study of innovative characteristics and economic indicators that could improve the performance of enterprises, lead to profit growth and expand market coverage. The paper systematized the factors that influence the diffusion of innovations. With their help, it is possible to manage the process of diffusion of innovations in a specific market and in a certain period of time. The use of the theory and methods for solving the thermal conductivity equation allows obtaining a solution to the problem of the diffusion equation, finding the optimal parameters for creating an innovative product susceptibility on the market.

“…Thermal conductivity is a measure of heat transferred across a unit thickness of a material in a direction normal to the surface ( Liao et al, 2018 ). In addition, thermal diffusivity is referred to as the thermal conductivity divided by the product of the density and heat capacity per unit mass at constant pressure ( Burlatsky et al, 2009 ; Diakonova et al, 2020 ). Therefore, if these two parameters are weak in an energy system, the heat transfer rate is weak.…”
