Toward a logistic model of dynamic mold growth on wood

Abstract This paper deals with mathematical modeling of mold growth on wood. The logistic equation is used to model phenomena in changing environmental conditions. Microscopic coverage fraction the represent development a material surface over time. current state-of-the-art dynamic Finnish as reference for model. optimal values coefficient are estimated by simulations under constant conditions and finding best agreement using optimization methods. It shown that can be approximated function relative humidity, temperature, wood species quality surface. parameters then verified comparison In this case, cyclic step changes humidity used. Finally, compared published experimental observations growth. discrepancy models data, possible improvements discussed.
