Abstract
Liquid mercury has been investigated as a potential high-Z target for the production of Muon particles for the Muon Collider project. This thesis investigates the dynamics of mercury flow in a design of the target delivery system, with the objective of determining pipe configurations that yield weak turbulence intensity at the exit of the pipe. Curved circular pipes with various half-bend angles, with/without nozzles in the exit region, and with/without welds on the pipe inner surface are studied. Theoretical analysis is carried out for steady laminar incompressible flow, whereby the terms representing curvature effects are examined. Subsequent simulations of the turbulent flow regime in the pipes are based on a realizable ${k}-{\varepsilon }$ Reynolds-averaged Navier-Stokes (RANS) equations approach. The simulations in this thesis have been based on the FLUENT commercial computational fluid dynamics (CFD) codes. The effects of turning angles, presence of a nozzle, and presence of a weld (on the inner surface of the pipes) on momentum thickness and turbulence intensity at the exit of the curved pipe are discussed, as are the implications for the target delivery pipe designs. It was found that the pressure loss from inlet to outlet is nearly the same for all pipes. A nozzle reduces the turbulence intensity of the flow while a weld increases it. | 197 pages
