Abstract:
The paper is devoted to numerical simulation of a system of turbular electric heating elements that are embedded in a steel plate (a press) basing on a slice of some other material, i.e. wood or MDF. Calculation purpose is to find the number and the power of heating elements that guarantee preselected heating regime of the press. In more detail, average temperature on the contact surface of the press and MDF is given, and temperature drop on this surface must not exceed some value determined by the properties of material under treatment. The simulation results are adopted by a certain company producing wood-fibre boards.
Keywords:initial-boundary problem for heat equation, mathematical modelling of technological processes, heating of a solid body, turbular electric heating element, finite-element method.
