W niniejszym artykule przedstawiono wirtualny model stanowiska, na którym symulowano pomiary przewodności cieplnej. Model wirtualny jest odzwierciedleniem stanowiska rzeczywistego. Symulacje zostały przeprowadzone w programie FEMM wer.4.2 i tym samym ukazano jego możliwości i ograniczenia. Przedstawiono wyniki pomiarów przewodności cieplnej wykonane na stanowisku rzeczywistym a następnie porównano je z wynikami badań modelu wirtualnego.

Virtual model of thermal conductivity measuring station is show in this article. Virtual model is based on real measuring station. Simulation is made using program called FEMM ver. 4.2. There is also shown the capabilities and limitation of this program. Results of simulation and real time measurements are introduced and compared.

Purpose: of this paper is to show a virtual model of thermal conductivity measuring station. Design/methodology/approach: Simulation has been made using finite element methods program called FEMM (Finite Elements Method Magnetics) ver. 4.2. Program has been created by David Meeker. Findings: Virtual model based on real measuring station is very helpful tool for engineering approach. Virtual model gives the possibilities of quick examinations of experiment, fast errors correction and possibilities of various experimentation without any cost losses. Research limitations/implications: The program for finite element methods modelling has its limitation. Boundary conditions and material properties has to be precisely given. Also heat losses has to be consider at all cost. Practical implications: The method applied in this work is also shown the capabilities, limitation and possibilities of this program. The prove of correctness of measuring station and simulation has been shown. Originality/value: The whole process of creating the model (drawing elements, defining materials, defining boundary condition and setting parameters of experiment) and running the simulation of thermal conductivity process has been presented. There is also shown the possible errors during model creation and its possibility of elimination.
