Comparison of ventilated air channels for historical buildings with moisture problems

The purpose of the research is to find adequate solution against rising damp in historical buildings. The improvement of this case is with ventilated air channel. Special part of historical buildings are churches because not use routinely this channels as for example museums, galleries. We designed 4 differently construction of ventilated air channel. These are: open or closed, with overpressure and underpressure. We use simulation software ANSYS CFX for verification relevance these construction. We modeled equal segments of the different construction. This research should be offer for architects the solution against problems of rising damp in historical buildings. For find the right solution is necessary to research everyone case. The aim of the research is to prepare the design process of the ventilated air channels for the architects without simulation every building, cross section or geometry of these construction.
