Sammendrag
The transport of fluid is one of the most important activities undertaken in
the human world. Back to the dawn of civilization where channels were
built to transport water for aggregation through to the modern world
where oil is pumped through an extensive pipe systems which traverses
continents on a global scale. It is an essential part of everyday life, but as
with all endeavors we undertake we encounter problems and difficulties,
many of which we have yet to overcome. Possibly the greatest problem
facing fluid transport is that of pipe clogging. For one of a magnitude of
reasons, solids can deposit upon the walls of a pipe or channel restricting
the space and resisting the flow. Over-time the buildup of such solids
becomes a major obstacle for the flow making the transport more and
more laborious until the entire process is forced to shut down.
In this thesis we study surface growth reactions that take place within
channel flow, leading to many beautiful patterns but also causing
eventual clogging, hindering flow transport. As such this work is a cross
disciplinary project be- tween physics, regarding flows and pattern
formation, and geology of the minerals and particles which solidify within
geological systems. Many of the samples and systems we study will be of
a geological nature, such as the transport of geothermal fluid within
power plants, this is then approached from a physics point of view with
simulations, analysis and theoretical predictions.
