The effect of heat convection on drying of porous semi-infinite space with a heat flux condition on the fixed face x=0

摘要

An analytic study is presented for rate processes, including change of phase for a semi-infinite porous substance exposed to a heat flux condition at x=0 of the type −q0/t,q0>0. Taking into account an inequality for the temperature at the interface x=s(t),Ts, an inequality for the coefficient q0 is obtained in order to have an exact solution. An equivalence between this problem and the analogous corresponding to a phase change problem with a temperature condition on the fixed face x=0 is also obtained.
