Acoustic is interdisciplinary science, that studies propagation of waves in gases, solids, fluids. Acoustic is presented in almost all aspects our life and engineering (noise, underwater acoustics, medical, architectural and musical acoustics, etc ). This course will cover recent advances in nonlinear acoustics, and some trends in computational nonlinear acoustics. Although linear acoustics is much easier to describe, however experiments showed that in real life nonlinear effects play important role and cannot be avoided. The current trends in the modern acoustic is to use nonlinear effects in order to increase the efficiency and accuracy of the methods or to improve the development of the devices. For example, second harmonic imaging can improve diagnostic ultrasound, nonlinear effects during focused ultrasound treatment can dramatically reduce the treatment time. Different nonlinear acoustic phenomenon will be described including radiation force, acoustic streaming, acoustic levitation, cavitation.
This course includes:
1. fundamentals of nonlinear acoustics
2. derivation and analysis of nonlinear equations
3. current cutting-edge trends in biomedical ultrasound
4. introduction to cavitation, acoustic-bubble interaction
5. some methods in computational acoustics
6. Special topics
