Numerical solution of an inverse diffusion problem for the moisture transfer coefficient in a porous material

A User-Friendly Tool to Characterize the Moisture Transfer in Porous Building Materials: FLoW1D

“…There is extensive experience in the field of inverse problems and parameter estimation. The works of Carmeliet and Roels [15], Roels et al [16], Gómez et al [17], Galván et al [18], Amirkhanov [19] and Rouchier et al [20] are examples of parameter estimation from laboratory tests. One of these approaches could be adopted together with the freeware codes included in the review by Delgado et al [8], or any other numerical solver, for the solution of the direct problem (simulation).…”

Molecular-dynamic simulation of water vapor interaction with suffering pores of the cylindrical type

“…The open face is 12 × 3 cm 2 . Similarly to work [Amirkhanov, Pavlušova, Pavluš 2008], we take values of water concentration in points x = 89.1; 88.2; 87.3; 86.4; 85.5 mm from the side of the open edge of the brick using the humidity distribution plot [Pleinert, 1998]. We get the following plot for these points at the left picture and corresponding approximation by the function w = a + be −t at the right picture (Fig.…”
