Experimental-based modelling and simulation of porous plant tissues under frost and condensation conditions (A01 [B01/B03])

The project focuses on the transport of heat and mass in porous plant structures in order to develop concepts for frost- and weather-resistant building materials. An accompanying mathematical framework has been developed by using a multiphasic continuum-mechanical model based on the Theory of Porous Media (TPM). In the second funding period, methods that allow the monitoring of freezing and thawing under controlled conditions (temperature, humidity) will be further developed, integrating results of B03 of the first funding period. The current TPM model will be extended by including microstructural effects for a comprehensive description of ice formation and subsequent applications for smart construction materials.
