Feasibility Study of Cooling a Bulk Acoustic Wave Resonator by Nanoparticle Enhanced Phase Change Material

The coupling of a cooling issue with the electromagnetic resonance of a bulk acoustic wave component is investigated in the current study. A new cooling technique is also demonstrated by the addition of nanoparticles to a phase change material surrounding the BAW resonator. The system's thermal behavior in first mode and various boundary conditions is investigated. As well, the effect of nanoparticles in quickening the BAW resonator cooling is shown.

An Aerosol Sensor for Multi-Sized Particles Detection Based on Surface Acoustic Wave Resonator and Cascade Impactor

This paper analyzed the impact of particle attachment of the chip on the mass loading effect, determined the optimal response area for particle attachment, determined the effect of the distance between nozzle and chip surface on particle transfer, and determined the collection efficiency of the specially built 2 LPM impactor using computational fluid dynamics simulation software. An experimental platform was installed to conduct the response experiment of the sensor to particle-containing gas generated by leaf fragment combustion and repeatability testing.
