Optimization of hydrodynamic cavitation using a model reaction

The decomposition of potassium iodide to liberate iodine, the model reactio n to study cavitational effects, has been carried out under different cavit ational conditions, The effect of various parameters (inlet pressure, flow geometry of orifice plates) on the iodine liberation rate has been studied. It is found that the flow geometry of the orifice plates considerably affe cts the rate of the iodine liberation. Recommendations are given for the ar rangement of the holes in order to achieve maximum benefits from the hydrod ynamic cavitation. The experimental results obtained in the present work ar e very much consistent with the results based on the theoretical model deve loped for the hydrodynamic cavitation. Due to this fact, it can be said tha t the model can be extended to any geometry of construction in the hydrodyn amic cavitation setup and will be helpful in designing cavitational reactor s.
