Abstract:
We perform several 3D fluid simulations of the LBNF cryostat using ANSYS CFX, a commercial Computational Fluid Dynamics (CFD) code. We calculate the Temperature, Velocity, and Impurity Distribution for the case when 4 pumps are on, circulating 103 gpm each, and discharging all to one location on the opposite end of the cryostat as the suction openings. We also calculate the same results with only 1 pump operational. A simulation for the positive Ion distribution with an 8 mm/s ion drift, and 1 pump operational will be added to the document once completed.
