CFD simulations using ANSYS Fluent were used to determine the coefficients of lift and drag, as<br>well as the frequency of vortex shedding and size of vortices at three separate Reynolds numbers of 16000,<br>32000 and 65000 in different arrangements. Each arrangement of cylinders was compared against controls,<br>which consisted of a single cylinder to determine the alteration of forces produced. Two trip wires at 7<br>different angles of 40, 45, 50, 55, 60, 65, and 70 degrees were then investigated at a Reynolds number of<br>65000 which was compared to the smooth cylinder control forces and frequency of vortex shedding. The<br>most optimum angle of trip wires was then combined with linear cylinder arrangements also at a Reynolds<br>number of 65000 for comparison with only the upstream cylinder utilizing the trip wires.<br><br></p> ER -
