• Chaotic mixing in two-dimensional square cavity flows with a periodic lid velocity was numerically simulated. To quantify the mixing in the cavity, the pseudo-Lyapunov exponent λ was measured. After selecting Reynolds number (Re) and amplitude of the lid velocity (A) as parameters which govern the flow field and mixing conditions, relationships between these parameters and λ were investigated. The obtained results showed that neither Re nor A affects the value of period T which gives the maximum λ.
