The wind tunnel experiments were conducted on a series of two-dimensional isosceles triangular cylinders of 28 mm base height and different vertex angles (2? = 30°, 60° and 90°), to study the distribution of unsteady static pressures in the wake region and to ascertain if they could be correlated. The velocity ranged from 5 to 15 m/s in the present study. The study reveals that the maximum coefficient of fluctuating pressures in the wake bears a constant ratio with base pressure coefficients for the models studied, and it is found to be 0.40. © 2005 Taylor & Francis Group, LLC.
