| چکیده مقاله |
| A curved-blade static mixer was designed and experimentally evaluated for inline mixing and fouling mitigation in Newtonian fluids within the transitional flow regime (Re = 2000–3000). Three spaced element arrangements (L/D = 0.75, 1.5, and 2) were investigated over a 10 cm tubular section. Mixing performance was quantified using the coefficient of variation (CoV), energy consumption through pressure drop, and fouling propensity via an empirical deposition index (DI). The L/D = 2 configuration (with four elements) reduced fouling by over 90% relative to an empty pipe while incurring negligible pressure drop, rendering it optimal for energy-constrained processes requiring adequate turbulence to suppress fouling. The L/D = 0.75 arrangement achieved superior mixing quality (CoV < 0.05). An empirical friction factor correlation, F=1.05×104×Re-1.18×(L/D)0.95, was developed, providing a unified description of the hydrodynamic behavior in both empty and mixer equipped pipes, with lower energy losses and favorable comparability to the conventional static mixers. |
