The acoustic radiation force on a spherical thermoviscous particle in a thermoviscous fluid including scattering and microstreaming
Bjørn G. Winckelmann, Henrik Bruus
We derive general analytical expressions for the time-averaged acoustic radiation force on a small spherical particle suspended in a fluid and located in an axisymmetric incident a…
Constant-power versus constant-voltage actuation in frequency sweeps for acoustofluidic applications
Fabian Lickert, Henrik Bruus, Massimiliano Rossi
Supplying a piezoelectric transducer with constant voltage or constant power during a frequency sweep can lead to different results in the determination of the acoustofluidic reson…
Determination of the complex-valued elastic moduli of polymers by electrical impedance spectroscopy for ultrasound applications
William N. Bodé, Fabian Lickert, Per Augustsson +1
A method is presented for the determination of complex-valued compression and shear elastic moduli of polymers for ultrasound applications. The resulting values, which are scarcely…
