تجزیه و تحلیل ریاضی فرآیند تبخیری از یک تکنولوژی جدید برای افزایش رطوبت در ساختمان های تاریخی

This work describes the moisture transfer process between a moving air flux and a saturated wall, by both advection and diffusion. Numerical solution of the partial differential equation describing moisture conservation gave the concentration field near the saturated surface and the mass transfer flux was integrated to give values of the Sherwood number as a function of Peclet number. A mathematical expression is proposed (given as Eq. (21) in the paper) to describe accurately the numerical dependence between the value of the Sherwood number and the values of Peclet number.
