FEASIBILITY OF USING EXPERIMENTAL LOAD MEASUREMENTS ON A CYLINDER TO PERFORM PHASE-SENSITIVITY ANALYSIS IN THREE-DIMENSIONAL FLOWS

The goal of this study was to evaluate the feasibility of addressing problems caused by three-dimensional vortical wakes when performing phase reduction analysis by using experimental direct load measurements on a cylinder. The outcome of this study is the validation of a method to use load measurements on a cylinder due to wake shedding to measure phase offset jumps and generate phase-sensitivity functions. Experimental data was collected using a recirculating water tunnel, custom translating test fixture, and load cell at the Naval Postgraduate School. Analysis of this data utilizes custom written MATLAB scripts to discern phase offset jumps from multiple trials for two different test conditions. Phase offset jumps and the location along a shedding cycle when the impulse occurred were used to generate phase-sensitivity functions for the two test cases. The study showed promising results and has proven the feasibility of using load cell measurements on a cylinder to create phase sensitivity functions for prediction of wake synchronization regions.
