Numerical analysis of two-dimensional heat and mass transfer during drying of cylindrical moist solids

Abstract EN

This paper deals with the numerical modeling of two-dimensional heat and moisture transfer during drying of a cylindrical moist object.

Drying is considered to be a process of simultaneous heat and moisture transfer whereby moisture is vaporized by means of a drying fluid (e.g.

air), as it passes over a moist object.

Numerical modeling of two-dimensional heat and moisture transfer during drying of a cylindrical object is carried out using an explicit finite-difference approach.

Temperature and moisture distributions inside a cylindrical product (i.e.

a date) are determined using the developed computer code.

Moreover, the results predicted from the present model are compared with the experimental data available in the literature for cylindrical broccoli and a considerably high agreement is found.
