IDEI Grant for exploratory research–Applying the thermodynamic method of irreversible processes to the optimisation of drying process of capillary porous materials. The project was financed by the National Council of Scientific Research in Academic Education (CNCSIS), in 2009-2010, with 215978.35 lei. In the project was used the thermodynamic method of irreversible processes to study the heat and mass transfer in boundary layer at the vaporisation surface of capillary porous materials during drying. The method allows to find out the boundary layer characteristics in terms of speed, temperature and concentration, as well as the phenomenological relations of heat and mass flux. An experimental drying bench was deployed as a closed circuit aerodynamic tunnel having a single sample. 35 Aerodynamic drying tunnel Project team: Assoc. prof.

CNCSIS Grant, no.945/2007, Environmental technology for the efficient and sustainable use of wood biomass as renewable fuel, a new approach in the field. The project focused on deployment of a new approach for the development of efficient and sustainable technologies of wood biomass as environmental and renewable fuels. There were processed samples made of different species of biomass and their combinations to find out the heating values measured experimentally with calorimetric bomb.
