Microwave Radiation Effect on Axial Fluid Permeability in False Heartwood of Beech (Fagus sylvatica L.)

Popis výsledku v původním jazyce

The purpose of this study was to evaluate the effect of microwave radiation on the fluid permeability and compression strength parallel to the grain of beech false heartwood. The European beech (Fagus sylvatica L.) was selected, and samples of false heartwood with dimensions of 30x20x20 mm3 were used. The microwave treatment was carried out in a laboratory device at a frequency of 2.45 GHz. The testing samples were divided into three groups (untreated, treated at 20-s intervals, and treated at 30-s intervals). The permeability was measured in the axial direction using distilled water. The coefficient of specific permeability was calculated using Darcy's law. The results showed that the coefficient of specific permeability increased by up to 159% in comparison with untreated samples. The compression strength parallel to the grain decreased by up to 15%.
