Abstract

In this thesis, numerical studies are carried out to understand the key factors affecting the effective fumigation in grain storage bunkers. This study is one of the first endeavours using numerical methods to investigate the tarpaulin billowing on bunkers. The mathematical model proposed covers many aspects of tarpaulin billowing mechanisms such as wind flow over bunkers, tarpaulin-formed structure deformation and fumigant transport in bunkers. The wind-induced tarpaulin deformation is modelled by the coupling of external wind flow and tarpaulin deformation.
