Visualization of Flow Past Inclined Bluff Cylinders

Abstract

Most of the engineering structures like buildings normally have either square, rectangular, trapezoidal or triangular cross-sectional shape. It is thus essential to know the aerodynamic loading, both in magnitude and frequency, on prismatic bodies. Some preliminary measurement had been carried out by the authors. The objective of the present paper is to conduct flow visualization to gain better understanding of the flow past prismatic bodies with different cross-sectional shape, which in turn will help the analysis of the experimental data.
