Abstract Silo-cave is a unique human habitation form on the Loess Plateau in northern China, which consists of an excavated 6–7 m deep pit as courtyard and cave dwellings surrounding four walls. This architecture has had history more than 7000 years, yet such “living fossils for dwellings” are now facing great crises challenges during rapid social economic development. In this paper, remote sen...

Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). In the present study, it is investigated if the observed ovalling oscillations can be numerically predicted. To this end, the silo structures are modeled using a finite element (FE) model and the w...

We present experimental results on the effect that inserting an obstacle just above the outlet of a silo has on the clogging process. We find that, if the obstacle position is properly selected, the probability that the granular flow is arrested can be reduced by a factor of 100. This dramatic effect occurs without any remarkable modification of the flow rate or the packing fraction above the o...

An explosion has recently occurred at a silo containing refuse-derived fuels (RDF) in Japan. There is a possibility that microorganisms are involved in generation of combustible gas from RDF and this study was aimed at showing the presence of bacteria that can ferment RDF pellets. All RDF samples tested contained a relatively high number of viable bacterial cells, 1.4x10(5) to 3.2x10(6) viable ...

Granular flow in a silo demonstrates multiple non-local rheological phenomena due to the finite size of grains. We solve granular fluidity continuum model quasi-two-dimensional geometries and evaluate its ability predict these effects, including spreading and, importantly, clogging (arrest) when opening is small enough. The augmented include free-separation criterion implemented numerically wit...
