METHODS AND SYSTEMS FOR TRANSPORTING VISCOUS FLUIDS IN A MOVING HYDROGEL TUBE

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.
