Abstract

Generalised integral transform technique (GITT) has been previously used to solve successfully multidimensional parabolic diffusive and diffusive-convective coupled problems. This approach is extended here to solve the 3-D Luikov's problem in parallelepiped .region for simultaneous heat and mass transfer. Filtering technique is employed to improve the convergence. The results illustrate the excellent convergence ratio for the eigenfunctions solutions of dimensionless temperature and moisture distributions. Graphics show the behaviour of the drying process.
