Modeling and Energy Consumption of Unilateral Heating Process of Flat Wood Details

A methodology has been suggested for mathematical modeling and research of two mutually connected problems: the temperature distribution along the thickness of flat wood details subjected to unilateral heating and the energy consumption of this process. For the realization of the methodology, a 1-di...

description	A methodology has been suggested for mathematical modeling and research of two mutually connected problems: the temperature distribution along the thickness of flat wood details subjected to unilateral heating and the energy consumption of this process. For the realization of the methodology, a 1-dimensional mathematical model has been created and solved for the transient linear heat conduction in flat wood details during their unilateral heating at arbitrary initial and boundary conditions encountered in the practice.
