Abstract
Understanding heat and moisture transfer in a wood specimen as used in the Ktester has led to an unconventional numerical solution and intriguing protocol to deriving the transfer properties Laplace transform solutions of Luikovs differential equations are derived for onedimensional heat and moisture transfer in porous hygroscopic orthotropic materials and for a gradual finite heat pulse applied to both surfaces of a flat slab The Ktester 637 Lasercomp supplies a quasiheatpulse to both sides of a 2ftsquare specimen and records precise signals as function of time from surface thermocouples and heat flux thermopiles We obtained transfer properties for moist and ovendried redwood lumber flooring
