A novel technique, which is a combination of the Laplace transform and matr
ix calculus, is employed to obtain the exact solutions of the linearized Lu
ikov system of coupled heat and moisture transport equations in a spherical
capillary porous body addressed to specified initial and boundary conditio
ns. It is shown that under certain restrictions, in the case of convective-
type boundary conditions, the transcendental equation yields a countable nu
mber of complex conjugate roots. Here, a new computational scheme is employ
ed, which evaluates real as well as a countable number of pairs of complex
conjugate roots. A set of benchmark results is generated for the Luikov dry
ing model, and in a way better than the alternative solutions proposed by L
obo er al. [19] for linear problems. Copyright (C) 1999 John Wiley & Song,
