Experimental and computational investigation of acoustophoretic effect in cylindrical vibro cleaner

Today’s world is moving towards the clean and green energy. Vibro Cleaner is developed based on ultrasonic technique to remove contaminations like rust, dirt, dust, oil etc. particles from the object surface. The process is eco-friendly towards the nature and completely safe for human. Vibro Cleaner has got notable impact in cleaning industries. The main goal of investigation is to examine behaviour acoustophoretic effect for finding erosion rate by introducing pressure acoustic transient model and validate by experimental investigation. Acoustic and Computational Fluid Dynamics (CFD) modules have been integrated to investigate sound pressure level, acoustic pressure, cavitation effect, particle trajectory and erosion rate in acoustophoretic environment. Piezoelectric transducer (PZT-4) of 40 kHz, which contains Lead zirconium titanate, has been sticked at bottom of steel tank which converts electrical signals into mechanical vibration and finally into pressure droplets by transience effect of tank wall in fluid. Pressure difference generates small tiny cavitation bubbles which strikes over the surface of object for cleaning. The particle sweep and erosive reaction have been scrutinised by applying particle tracing and fluid flow wear erosion modules. Experimental investigation also has been accomplished to validate the computational outcomes. The placement of object in steel tank is also one of the important factors to check the efficacy of cleaning process which has been checked at various height. The practical result erosion rate has been compared with simulation results. The experimental investigated result validates the computational simulation by achieving satisfactory out comes.
