Abstract:
Document shows results of a Computational Fluid Dynamics (CFD) model of the 10kT cryostat. The cryostat liquid circulation was modeled using ANSYS CFX commercial CFD code. Results are shown for temperature and impurity distribution, velocity profile, pressure/force distribution on the CPA planes from the buoyancy driven fluid, as well as Liquid surface velocity and evaporation contour. The preliminary model is a 2D symmetric cross section of the cryostat, which may be further analyzed as 3D if computational resources are sufficient.
