Description

High speed pumps are not only important for cryogenic propulsion but also
experience a growing interest for a wide range of more industrial applications.
Although in use since long time, a large amount of research is still going on to
improve the performance, operating range and reliability. Stationary and instationary
operations are still challenging aspects of pump design and operation. The objective
of this special course is to review the state of the art on: optimum design methods for
impellers and return channels, including tip clearance effects and casing treatment;
performance prediction related to the NPSH over the entire operating range; stationary
and unsteady cavitation and their relation to synchronous and asynchronous vibrations;
start up and stop; interaction of pump with the fluid circuit and inlet distortion;
thermal effects due to cryogenic fluids. Advanced numerical simulations as
well as non-intrusive experimental techniques and embarked pressure transducers
measurements will be presented. (RTO-AVT-VKI Lecture Series)
