Computational Fluid Dynamics in Support of the Large Cavitation Channel
Abstract
The objective of this project is to use computational fluid dynamics to examine the flow around three Schiebe head forms: 2 inches, 10 inches, and 20 inches in diameter. The flow around the 20-inch head form was examined experimentally in the Large Cavitation Channel by making laser Doppler velocimetry measurements. Computational analysis was used to determine the flow around all three head forms. The computational results and the experimental results were compared. The objective of the comparison was to determine if a computational model could be used to represent accurately a physical model in a test tunnel. The results showed that both viscous and inviscid flow calculations represented the experiment well. The inviscid analysis was much less costly in time and resources while still providing useful results. inviscid flow calculations seem to be the best choice for a preliminary prediction technique to support experimental investigations. This report presents a description of the experimental and computational methods used, a detailed comparison of results, and an analysis of the comparison. computational fluid dynamics, Large Cavitation Channel, Schiebe, cavitation head forms, laser Doppler velocimetry.
