Experimental Study on Pressure Distributions around a Circular Cylinder in the Branch of a T-junction

Abstract

The mean pressure distributions of a single circular cylinder in the branch of a T-junction are experimentally investigated with intelligent pressure scanners (PSI 9116) in wind tunnel. Experimental data of the circular cylinder in a straight duct are conducted to provide a benchmark. Mean pressure distributions of the circular cylinder are obtained at different positions along streamwise direction under the velocity ratio (R) ranging from 0.117 to 0.614. Two dimensionless parameters including correlation coefficient (
