USING DISCRETE-CONTINUOUS APPROACH FOR THE SOLUTION OF UNSTEADY-STATE MOISTURE TRANSFER EQUATION FOR MULTILAYER BUILDING WALLS

Moisture regime of enclosing structures is one the most complicated and controversial directions in construction industry. Temporary climate impact on low moisture inertia building materials lead to situation which it impossible calculate steady-state regime. Numerical methods are usually used assess behaviour structures. In current paper, a differential equation transfer formulated. The solution unsteady-state was obtained using discrete-continuous approach. Thus, formula allows scientists multilayer walls buildings obtained. A two-layer structure with aerated concrete base mineral wool insulation calculated.
