dc.description.abstractTHIS STUDY AIMED TO DEVELOP A MODEL USING EXPERIMENTALLY OBTAINED CONVECTIVE HEAT AND MASS TRANSFER COEFFICIENTS TO PREDICT THE EFFECT OF TEMPERATURE, HUMIDITY, AND DRYING RATE ON WOOD DRYING. TANGENTIAL WOOD SAMPLES OF EUCALYPTUS NITENS (H. DEANE & MAIDEN) WERE USED IN THE INVESTIGATION. THE EXPERIMENTAL DESIGN CONSISTED OF TWO TEMPERATURE LEVELS (40 ?C AND 55 ?C), TWO RELATIVE HUMIDITY LEVELS (55% AND 75%), AND TWO AIR VELOCITY SETTINGS (2 M·S?1 AND 3 M·S?1). THE EXPERIMENTS WERE CONDUCTED UNDER A CONSTANT EVAPORATION RATE, SPANNING THE MAXIMUM AND CRITICAL MOISTURE CONTENT IN THE WOOD. A STATISTICAL MODEL USING MULTIVARIATE REGRESSION WAS CREATED TO PREDICT THE CONVECTIVE HEAT AND MASS TRANSFER COEFFICIENTS. THE RESULTS INDICATED THAT THE EXPERIMENTAL DATA AND EMPIRICAL CORRELATIONS EXHIBITED AN ERROR MARGIN OF 37.77% AND 37.86%, RESPECTIVELY. A SIGNIFICANT POSITIVE CORRELATION WAS FOUND BETWEEN THE CONVECTIVE HEAT TRANSFER COEFFICIENT AND AIR VELOCITY, TEMPERATURE, AND RELATIVE HUMIDITY, WHILE THE CONVECTIVE MASS TRANSFER COEFFICIENT SHOWED A SIGNIFICANT POSITIVE CORRELATION ONLY WITH AIR VELOCITY AND TEMPERATURE. THE MODEL PREDICTED THE CONVECTIVE HEAT AND MASS TRANSFER COEFFICIENTS WITH HIGH ACCURACY AND STATISTICAL SIGNIFICANCE. USING THE PROPOSED METHOD, WE SUCCESSFULLY OBTAINED BOTH CONVECTIVE COEFFICIENTS, WHICH ENABLE ACCURATE DESCRIPTION OF HEAT AND MASS FLOW DURING THE CONVECTIVE DRYING OF EUCALYPTUS NITENS WOOD.
