Description
The occurrence of pressure and flow fluctuations in fluid flow systems with heat addition has been noted in many isolated instances. Under certain conditions of local "boiling, which includes a boiling-like mechanism at super-critical pressures, intense sounds and mechanical vibrations can be generated. A mechanism for these fluctuations is derived based on fundamental considerations. A large change in density with enthalpy, such as occurs at a liquid to vapor phase change point or in the super-critical region, will.introduce a flow transient. Changes in the frictional resistance to flow can also initiate a transient condition.
