A method for transporting a material (which may be a viscous fluid) in a conduit defined by a conduit-defining surface comprises: flowing a first fluid and a second fluid in a flow direction within the conduit; contacting the first and second fluids to one another at a contact region to thereby facilitate a reaction creating a reaction product in an interface region that extends downstream from the contact region, wherein the reaction product is an elastic-solid; and transporting the material in the flow direction within the conduit. At locations downstream of interface region, the reaction product creates a barrier between the viscous fluid and the conduit-defining surface.

Methods and systems for transporting viscous fluids in a moving hydrogel tube

Particles are separated from a source viscoplastic fluid by flowing streams of the viscoplastic fluid and a destination fluid in parallel streamed relationship inside a rotating cylindrical annulus by using baffles to introduce each fluid independently at an inlet lower end of the annulus and for separating the upper streams consisting of an un-yielded source and destination flow proximate the radially innermost side of the annulus, a bulk axial flow in a more central region and a yielded layer destination flow adjacent the radial outermost side of the annulus which contains the particles that have separated. Inlet and outlet baffles are provided at each end of the vertically oriented device to maintain the flows discrete on entry and to maintain the separated flows discrete on exit so as to facilitate removal of the component flows from the fractionator.
