WebJul 21, 2024 · Abstract. We consider a thermoelastic theory where the heat conduction is described by the Moore–Gibson–Thompson equation. In fact, this equation can be obtained after the introduction of a relaxation parameter in the Green–Naghdi type III model. We analyse the one- and three-dimensional cases. WebThe energy balance method (latent heat flux) is calculated as the residual term in the general energy balance equation. 14. 4.2 Aerodynamic Method. 15 The first factor controlling the evaporation is the heat energy which was the main concern of the Energy balance method, but the second controlling factor is the ability to transport vapor. boat rockerz 558 sunburn edition https://gameon-sports.com

WebIt is remarkable that if we adjoin equation (1.3) to (1.1), we obtain the linear version of the Moore-Gibson-Thompson equation. When k = 0 we recover the Cattaneo-Maxwell heat equation. Given a heat conduction theory a thermoelastic counterpart can be developed. Therefore from this new thermal equation we can propose a thermoelastic theory.
