dc.description.abstractEmission of surface water on wood should be controlled because moisture movement on the
wood surface initiates changes in its morphological, physical, chemical, and biological properties. In this
study, surface moisture content (SMC) of yellow poplar (Liriodendron tulipifera L.) wood was measured
by a near-infrared spectroscopy (NIRS) technique, nondestructively and continuously, during unsteadystate
desorption conditions. With these SMC data, surface emission coefficients (SECs) were determined
continuously while the wood was being dried. These experimentally determined coefficients were compared
with values that were converted from the theoretically determined mass transfer coefficients. The
conversion method, which was developed to facilitate a comparison among the mass transfer coefficients,
indicated that the boundary layer theory was useful in evaluating the degree of external moisture resistance
while the wood dried. Also, the NIRS technique can be used for determining SEC at each specific
point of wood, experimentally, in real time.
