A New Proposed Return Guide Vane for Compact Multistage Centrifugal Pumps
International Journal of Rotating Machinery, 2013 For widely used multistage centrifugal pumps, their former structures are so bulky that nowadays growing interest has been shifted to the development of more compact structures. Following this trend, a compact pump structure is provided and analysed.

Insights in thixotropic concrete pumping by a Poiseuille flow extension
Applied Rheology, 2020 Thixotropy is a reversible time-dependent phenomenon in fluids, in which an internal structure grows due to flocculation and breaks down under shear action. Numerous fluids are thixotropic, e.g. concretes and cementitious suspensions. Pumping of concrete

Displacement Pumping of Liquids Radially Inward on Centrifugal Microfluidic Platforms in Motion
Micromachines, 2011 We describe two novel centrifugal microfluidic platform designs that enable passive pumping of liquids radially inward while the platform is in motion. The first design uses an immiscible liquid to displace an aqueous solution back towards the center of ...
