AN ALTERNATIVE CHOICE FOR THE DRYING VARIABLES LEADING TO A MATHEMATICALLY AND PHYSICALLY WELL DESCRIBED PROBLEM

Dry air density, moisture content and thermal mass are the three indep endent variables used to produce a relevant physical description of he at, mass and momentum tranfer that occur in a capillary porous medium during drying processes. This choice leads to a conservative set of eq uations. This strongly coupled and highly non-linear system is solved numerically by focusing on the accuracy of the solution and on a time step procedure to enable faster processing time.
