The hysteresis phenomenon from two tandem square cylinder in the proximity of a solid wall, Re=150.

The hysteresis phenomenon occurs in a special range of the cylinders spacing. In this case, two different values are observed at each distance for different quantities such as lift and drag coefficient, Strouhal number and Nusselt number.
