Abstract:
This study investigates enhanced fluid velocity induced by megasonic waves (2.4 MHz) in silicone fluid, using single and dual-ultrasound setups with varying propagation angles (0°, 30°, 40°, 50°). Particle Image velocimetry (PIV) was used to measure the flow fields in a chamber. Results show that dual-ultrasound configurations, particularly at a 30° propagation angle, significantly enhance fluid velocity compared to single-ultrasound. It is also achieved a maximum average velocity of approximately 6.75 cm/s at a specific location. This enhancement is attributed to optimized interaction between the ultrasound waves and the fluid, maximizing flow dynamics. The findings suggest that dual-ultrasound systems, offer significant potential for enhancing fluid mixing and transport in various applications. Future research will focus on further optimizing these configurations for practical use.
