Sensitivity analysis of mathematical model suitable for description of biofilms growth

Popis výsledku v původním jazyce

Biofilms growth on surfaces of building material can affect not only their appearance, but also a hygrothermal performance. Prediction and description of biofilms growth is therefore of a significant importance. Computational modelling represents an optimal approach for this purpose. The computational outputs are dependent on quality of input data, material properties in particular. This paper deals with a sensitivity analysis of a selected mathematical model for coupled heat and moisture transport that can be used for biofilms growth description by means of its growth rates functions extension. Within the analysis, an influence of variance of hygric material properties on output produced is studied. A block made of autoclaved aerated concrete exposed to climatic conditions of Prague, Czech Republic was assumed. It was found, that temperature difference when compared to reference results may differ up to 0.555 °C and relative humidity up to 6.42 %. Such results predispose the model to be a good candidate for a biofilms growth description.
