| Abstract | A fast-response Cobra probe is a specialized flow measurement instrument, developed by Turbulent Flow Instrumentation of Australia as described in Hooper and Musgrove (1997). This instrument is extremely useful for the study of bluff body wakes because it senses three-components of flow speed at high frequency with a small measurement head. It is inexpensive and easy to use and is therefore an excellent choice for flow measurement projects where time and budget are major considerations. However, Cobra probes have a limitation on flow angle measurement that can lead to incomplete data sets for highly turbulent flows. Using a recent ship-airwake experiment as an example, this paper shows how probability distributions of turbulence can be used to increase the usefulness of Cobra data in highly turbulent flows by providing additional insight into the flow characteristics that are affected by the limitation. The concepts shown in this paper are useful both for the analysis of flow characteristics and for validation of computational fluid dynamics (CFD). |
