Scale-up of vortex based hydrodynamic cavitation devices: A case of degradation of di-chloro aniline in water

Hydrodynamic cavitation (HC) is being increasingly used in a wide range of applications. Unlike ultrasonic cavitation, HC scalable and has been at large scale industrial However, no information about influence on performance available the open literature. In this work, we present for first time, experimental data use degradation complex organic pollutants water four different scales (~200 times scale-up terms capacity). Vortex based devices offer various advantages like early inception, high cavitational yield significantly lower propensity to clogging erosion. We have vortex work. 2,4 dichloroaniline (DCA) – an aromatic compound with multiple functional groups was considered as model pollutant. Degradation DCA performed using vortex-based characteristic throat dimension, dt 3, 6, 12 38 mm almost 200 time flow rates (1.3 247 LPM). Considering constraints operating largest device, presented here only one value pressure drop across device (280 kPa). A previously per-pass extended describe pollutant study generalised form presented. The found decrease increase then plateaus. Appropriate correlation developed data. approach results provide sound basis set further development comprehensive multi-scale modelling devices.
