Characteristics of Flow around a Modified Square Prism

Abstract:

The present investigations focus attention on PIV measurements and three-dimensional numerical investigation on flow past a modified square prism with a sinusoidal surface. The detailed near wake vortex structures and velocity fields of such modified square prism are captured and compared with a straight square prism in the same flow conditions. The three-dimensional free shear layers behind the modified square prism extend further downstream and become more stable than those of the straight one. For a modified square prism, significant mean drag coefficient reduction and fluctuating lift suppression are obtained at the Reynolds numbers of 600 and 5900. It indicates that such modified square prism is capable of minimization of flow induced vibration and force reduction.
