Experimental study and mathematical modelling of biofilter aerodynamic resistance

Abstract

Development of industry is not always accompanied with the implementation of clean technologies, thus the problem of air and water purification remains. For the moment, pollution with different paint components is widely spread and hard to be solved. A biofilter was developed at the Department Environmental Protection of Vilnius Gediminas Technical University (VGTU), and its chemical and physical purification principles and properties are analysed in works [1–3]. Besides the efficiency of pollutant cleaning, the characteristics of filter aerodynamic resistance are also essential, therefore, the aerodynamic properties of the biofilter are analysed in this work. For anticipation and theoretical evaluation of aerodynamic processes going on in a biological air-purification device, the processes occurring in the object being investigated – a biofilter – were modelled with the help of Phoenics, Versions 3.2 and 3.5. Aerodynamic processes – in-coming flow velocity and aerodynamic charge resistance – were analysed with the help of the software package Phoenics, Versions 3.2 and 3.5. Modelling was based on mathematical equations that describe physical laws.
