Abstract
A method of moving materials comprises: flowing a first fluid in an axial direction, the first fluid characterized by inertial forces dominating viscous forces of the first fluid; flowing a second fluid in the axial direction, the first and second fluids miscible with one another and the first and second fluids having an interface region therebetween; permitting a reaction to create a reaction product in the interface region, the reaction product mitigating flow-disrupting mixing between the first and second fluids.

A method of moving materials to create a reaction product, the method comprising:
- flowing a first fluid in an axial direction;
- flowing a second fluid in the axial direction, the first and second fluids miscible with one another and the first and second fluids having an interface region therebetween;
- and
- permitting a reaction to create a reaction product in the interface region, the reaction product mitigating flow-disrupting mixing between the first and second fluids;
- wherein inertial forces of the first fluid are greater than viscous forces of the first fluid such that a Reynolds number of the first fluid at an axial location corresponding to an upstream-most extent of the interface region is greater than 500.
A method of moving materials to create a reaction product, the method comprising:

- flowing a second fluid in the axial direction, the first and second fluids miscible with one another and the first and second fluids having an interface region therebetween;
- and
- permitting a reaction to create a reaction product in the interface region, the reaction product mitigating flow-disrupting mixing between the first and second fluids;
- modifying one or more of a first fluid inlet velocity and a second fluid inlet velocity to control a cross-sectional dimension of the reaction product;
- wherein inertial forces of the first fluid are greater than viscous forces of the first fluid such that a Reynolds number of the first fluid at an axial location corresponding to an upstream-most extent of the interface region is greater than 100.
