Chapter 4 Case Study: Simulation of an AUV Propeller As introduced in chapler 2, D'Epagnicr designed an AUV propeller by OpcnPVL code. In this chapter, the OpcnPVL_SW code was run with the same parameters as in D'Epagnier's study, and generated a propeller geometry file for SolidWorks. Because OpenPVL and OpcnPVL_SW have the same calculation methods ofpropcllcr design, the propeller geometry is the same. The main purpose ofthis case study is to verify that the OpenPVL_SW code is not only capable ofgenerating a propeller geometry file for SolidWorks, bUI also the CosmosFloWorks can achieve reasonable simulation results for predicting propeller thrust. After running the propeller design function with the propeller parameters in Opcnl>VL_SW, the OpcnProp_Solidworks.txt file was created to generate the propeller blade in SolidWorks. This file records the macro to automotically drow the propeller blade geometry in Solidworks. An abbreviated version ofthe macro is shown in Appendix B. The propeller blade geometry is shown in Figure 40. 76
