Numerical modelling of hygrothermal response in building envelopes

Numerical modelling of hygrothermal response in building envelopes

The present paper deals with numerical modelling of heat and mass transfer through multilayer walls. Based on physical principles of mass and energy conservation, nonlinear partial differential equations are developed, where driving potentials are considered. Measurable physical properties involved...
