“…While the effect of temperature on the performance of SSTs has been studied with CFD models in the last 30 years, few studies show the effect of surface wind. Several recent CFD researchers studied the surface wind effect on rectangular settling tanks in WTPs (Gkesouli, Nitsa, Stamou, Rutschmann, & Bui, ; Gkesouli & Stamou, ; Goodarzi, Lari, & Alighardashi, ; Khezri, Biati, & Erfani, ; Stamou & Gkesouli, ). However, the applicability of these studies to SSTs in WWTPs is limited due to (a) the structural difference between SSTs in WWTPs and settling tanks in WTPs, (b) different solids settling processes, and (c) different solids concentration.…”
