Experimental study on the effects of acoustic streaming of high frequency ultrasonic waves on convective heat transfer: Effects of transducer position and wave interference

In the present study, an experimental study was carried out in order to find the effect of high frequency ultrasound wave transducer position on heat transfer rate. For this purpose, a thin platinum wire, which was used as a heater and sensor, was submerged in deionized water. The high frequency ultrasound transducers were installed at various positions including; two on lateral wall and three at the bottom of a cylindrical container. The interference effects of multiple transducers were investigated and it was found that a single transducer installed at the lateral wall works more efficiently than other layouts from heat transfer enhancement point of view.
