The Fluid Dynamics of Mercury Target Delivery and Exhaust for A Muon Collider Particle Production System.

摘要

iquid 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
