abstract

Presented research is a continuation of the our previous work [1], where numerical modelling tools are applied to study relation between the moisture distribution and related stress and strain in painted wooden desks. In this paper, the very simply linear model for modelling of the stress in the wood is substituted by more complex model. Used stress model is based on St. Venant – Kirchhoff-material and stress/strain relation in the form of Hooke’s law for small strains presented in [2]. Furthermore, the previous 3D CFD model of the Chapel of the Holy Cross at Karlstejn Castle is completed by added the influence of the visitors on the indoor climate. Same as in the previous above cited work, the temperature and relative humidity distribution in the chapel is obtained by FLUENT 3D CFD model of the chapel and these results are post-processed and used as boundary condition for the calculation part, which is performed in the MATLAB. This problem is being investigated as one of the tasks of the European project Climate for Culture (http://www.climateforculture.eu/).
