Heat and Mass Transfer in a Dense Layer during Dehydration of Colloidal and Sorption Capillary-Porous Materials under Conditions of Unsteady Radiation-Convective Energy Supply

Mathematical Modeling of Heat and Mass Transfer during Moisture–Heat Treatment of Castor Beans to Improve the Quality of Vegetable Oil

“…The models differ in the number of equations simulating the temperature state of the material and moisture transfer, as well as in the method of determination of the intensity function of phase transformations of liquid and vapor at the internal points of the porous body. The most common methods use the phase transition coefficient [12][13][14][15] or the mass transfer equation of the liquid phase [17][18][19][20][21][22][23][24][25], which require the moisture content function, the correct determination of which, without knowing the intensity of the phase transition, is somewhat problematic.…”

“…It has a numerical implementation. From the equation of wet and heat transfer [17], a mathematical model of the drying kinetics in a thin dispersed layer was developed, including the radiative-convective energy supply. In [18], the above equations are solved analytically using an empirical approach and taking into account material shrinkage.…”

“…Numerical implementation of these approaches requires a significant amount of experimental data to determine the thermophysical parameters of the material and mass transfer characteristics. Moreover, the accuracy of mathematical modeling is significantly reduced if the equations of the energy and mass transfer [14,17,18] are solved independently, and the thermophysical characteristics of the material in the process of frying are considered constant.…”
