Advanced reduced-order models for moisture diffusion in porous media
Suelen Gasparin, Julien Berger, Denys Dutykh +1
It is of great concern to produce numerically efficient methods for moisture diffusion through porous media, capable of accurately calculate moisture distribution with a reduced co…
On the estimation of moisture permeability and advection coefficients of a wood fibre material using the optimal experiment design approach
Julien Berger, Thomas Busser, Denys Dutykh +1
This paper presents a practical application of the concept of Optimal Experiment Design (OED) for the determination of properties of porous materials with in-situ measurements and…
Solving nonlinear diffusive problems in buildings by means of a Spectral Reduced-Order Model
Suelen Gasparin, Julien Berger, Denys Dutykh +1
This paper proposes the use of a Spectral method to simulate diffusive moisture transfer through porous materials as a Reduced-Order Model (ROM). The Spectral approach is an a prio…
An efficient method to estimate sorption isotherm curve coefficients
Julien Berger, Thomas Busser, Denys Dutykh +1
This paper deals with an inverse problem applied to the field of building physics to experimentally estimate three sorption isotherm coefficients of a wood fiber material. First, t…
An improved explicit scheme for whole-building hygrothermal simulation
Suelen Gasparin, Julien Berger, Denys Dutykh +1
Implicit schemes require important sub-iterations when dealing with highly nonlinear problems such as the combined heat and moisture transfer through porous building elements. The…
Stable explicit schemes for simulation of nonlinear moisture transfer in porous materials
Suelen Gasparin, Julien Berger, Denys Dutykh +1
Implicit schemes have been extensively used in building physics to compute the solution of moisture diffusion problems in porous materials for improving stability conditions. Never…
