3D VISUALIZATION OF THE DEFROSTING PROCESS OF BEECH PRISMS IN THE VENEER PRODUCTION

Abstract

The paper presents a new approach for the 3D colour visualization of the obtained with the help of own mathematical model calculated results about the non-stationary temperature distribution in the volume of frozen wood materials with prismatic shape during their defrosting. An example for the application of the approach for visualization of the temperature distribution in frozen beech prisms with thickness 0,4 m, width 0,4 m, length 0,8 m, initial temperature -40 оC, and moisture content 0,3 kg.kg-1 (wood with ice from the bounded water in it) and 0,6 kg.kg-1 (wood with ice from both the bounded and the free water in it) during their defrosting at temperature of the processing medium 80 оC has been given. The results from the studies can be used for the creation of an optimal energy saved thermal treatment of prismatic wood materials during their defrosting with an aim of following plasticizing in the veneer production.
