Experimental Investigation on the Thermal Performance of a Novel Hydrodynamic Cavitation Reactor
Even though the effect of hydrodynamic cavitation has been confirmed in many previous studies in the past twenty years, the hydrodynamic cavitation reactors (HCRs) used in these studies are less effective, which are inappropriate to apply them to the real large-scale industrial disinfection applications. In the present study, we proposed an experimental investigation of the thermal performance of a novel, advanced, rotational HCR. Firstly, analyses of the flow field and cavitation generation mechanism in the HCR were conducted via visualization of the reactor flow field using a high-speed camera. Secondly, the thermal performance was tested by 20 experiments with various rotational speeds of the rotor (2700, 3000, 3300, and 3600 rpm) and pump pressure settings (0.0, 0.5, 0.7, 1.0, and 1.5 bar gauge pressure). The HCR maximally achieved 48149.26 kJ/h in the heat generation rate and 82.18% in the thermal efficiency. The effects of the pressure setting and rotational speed on the performance were discussed in detail. Increasing the pump pressure setting (flow rate) caused increases in the heat generation rate, electric consumption rate, and thermal efficiency. Increasing the rotational speed considerably increased the flow rate, heat generation rate, electric consumption rate, and thermal efficiency.
