摘要
The study progress of heat and moisture transfer within fabric is reviewed. For the time area, a mixed algorithm with precise time integration and finite difference for solution of a transient thermal and humidity field in porous fabric is presented.For space area, the finite element is applied. To avoid the unreasonable phenomena such as jump or vibratility in initial time step for solution thermal and moisture equations by finite element, the lumped mass heat capacity matrix and moisture capacity matrix is applied. The sorption or desorption rate of water by the fibers is considered as collection or source and a scheme of the predigested precise time integration is advanced.
