“…Another example of the use of this method can be found in Lima et al [8] These authors used a finite volume method to describe the drying process of peeled bananas considering shrinkage and an ellipsoidal configuration for the product. Several numerical solutions of the diffusion equation using finite volume for various geometries are available in the literature; for example, the solutions proposed by Silva et al [22][23][24] (arbitrary geometry, boundary condition of the first kind; arbitrary geometry, boundary condition of the third kind; and sphere, boundary condition of the third kind, respectively).…”

“…In the case of a variable transport coefficient C U , a harmonic mean will be used for its estimation at the interfaces of each control volume [17,18]. At the nodal points, C U must be calculated by an appropriate function that relates C U with the value of U at each nodal point.…”

“…In many areas of production involving heat and mass transfer, there are many situations in which the solids under study do not present regular geometry [17][18][19][20][21][22][23][24][25][26]. Some examples can be cited: sanitary ware, some types of coating, tile, rice, wheat, lentil, pumpkin and cashew.…”

“…They concluded that numerical simulation provided an accurate prediction of heat and mass diffusion inside spherical foods with variable properties that were almost impossible to obtain with analytical solutions. Da Silva et al [78] proposed the use of the FVM to investigate the two-dimensional heat and mass diffusion for cowpea grain during drying. The diffusion equations were discretized with a fully implicit formulation, generalized coordinates, and boundary condition of the first kind.…”
