Evaluation of effective conductivities for masonry with interfaces
Original language description
Evaluation of effective or macroscopic coefficients of thermal conductivity under steady state conditions is presented. In computational homogenization there are three levels at which the field quantities are to be averaged. Solving a set of problem equations on micro-scale (at the porous or microscopic level) provides us with the up-scaled equations for the homogenization on meso-scale. At this meso-structural or mesoscopic level masonry is treated as a composition of stone blocks or bricks and mortar(joint) and its homogenization produces the macroscopic equations which may be used when analyzing a masonry building and/or a bridge as a whole (macroscopic analysis). The main concern of this contribution is the modeling of transport phenomena on meso-scale. Special attention is paid to the description of heat transport across interfaces between stone blocks (bricks) and mortar, which in classical models is mostly not dealt with.
