Modeling and experimental investigation of the heat and moisture transfer in the process of microwave-convective drying of vegetable materials

Mathematical Modeling of Heat and Mass Transfer in the Drying of Granules Used as a Support for a Nickel Catalyst

“…The authors of [12][13][14] based their studies on the diffusion-filtration model developed by A.V. Luikov [3], which makes it possible to study interrelated heat and mass transfer in a capillary-porous medium.…”

Generalization of the Wet-Bulb Temperature Notion to the Case of Electromagnetic Drying

“…At one and the same effective intensity of the electromagnetic radiation S eff and, therefore, at one and the same intensity of drying J ∞ , depending on the fractions of the HF, MW, and IR radiation components, the distributions of the temperature and the moisture-content of the material of the plate take different forms (for the function T (x), this follows from formulas (16), (18), and (22)), which can be used for optimization of the drying process [9,13,14].…”

“…In [15][16][17][18], different opinions on the factors providing the intensifi cation of drying of a body in the case where it is subjected to the action of electromagnetic radiation are presented. It is commonly suggested that the indicated intensifi cation is mainly due to the following two factors: a) because of the absorption of electromagnetic radiation by the material of a body, the rate of transformation of the water in it into the vapor increases sharply; b) in the case of action of electromagnetic radiation on the body, the gradient of the temperature fi eld in it changes its direction and a pressure drop arises inside the body, which leads to a sharp increase in the density of the moisture moving to the surface of the body.…”
