Abstract: The application of a splitter plate on square cylinders to reduce drag in cross-flow is an active research area. However, the associated aeroacoustic sound in the surrounding fluid also undergoes reduction, an aspect which has received less attention. This paper presents a numerical methodology for coupled aerodynamic and aeroacoustic calculations for flow past square cylinders with various splitter plate lengths. Computations are performed at a Re of 22000 using URANS technique and FW-H analogy. Observing that drag reduction and sound reduction occur at different splitter plate lengths, a two-objective optimization problem is posed to minimize the drag and OASPL simultaneously.
