Experimental Setup

A schematic drawing of the experimental setup is shown in Figure 3.8. It comprises the following components: flow circuit, traversing mechanism for hotwire measurements, laser (pulsed), CCD camera, seeding arrangement for PIV measurements, and data acquisition system. The free-stream velocity approaching the cylinder has been determined using a pitot-static tube connected to a micro-manometer. The micro-manometer has a resolution of 0:001 mm of it translates to an error in Reynolds number of about The details of the test cell are discussed here and the PIV and HWA techniques are presented in the following section.
