  • Abstract

    Hydrodynamic analysis of flow around square cylinders at different inclined angles of attach ranging from 0 to 45 at low Reynolds numbers, both in water and air, has been carried out using commercial software ANSYS CFX. Twenty different square cylinders were modeled at angles 0, 5, 10, 15, 20, 25, 30, 40 & 45 degrees. Results obtained by the hydrodynamic analyses were analyzed by Eureqa software to find a relation between non dimensional parameters. Strouhal number was determined to be a function of angle of attack and 1/Re in water and air. The obtained formulas were tested at two random angles of 33 and 50 against the results of Ansys-CFX. Comparison displayed good agreement which is demonstrative of the acceptability of the obtained relationships.
