Thermal acoustic oscillations in cryogenic systems.

Author(s) : GU Y., TIMMERHAUS K. D.


Thermal acoustic oscillations are often observed in tubes that are closed at the warm end and open at the cold end when inserted into a cryogenic system. The stability characteristics of thermal acoustic oscillations in liquid helium and hydrogen systems have been predicted theoretically by solving the perturbed and linearized hydrodynamic equations. Experimental verifications have been performed to validate these theories in a liquid helium system.
