Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical model will be used to compare different configurations; changing the Height (H), diameter (D) of the reactor and the probe immersion depth (d). To compare the results, a new variable ‘Aα’ is defined. It quantifies the area favorable for cavitation i.e, where the cavitation threshold is breached. The results obtained will be used to find the ideal configuration which results in maximum pressure field.
