Flow behavior in pneumatic conveying systems involving a binary particle mixture

摘要

It is well known in practive that the particle size distribution (PSD) plays a key role in the pressure drop required to convey a given gas-solid mixture. In this work we attempt to elucidate the mechanism goveming the flow behavior of solids with a psd by considering the simple case of a bimodal particle mixture. We consider two types of bimodal mixtures.
