Organized Sessions and Session Scope
(1)Workshop on physical models and CFD tools for computation of
cavitating flows
(Jean-Pierre Franc <Jean-Pierre.Franc@hmg.inpg.fr>,
Guenter H. Schnerr<schnerr@flm.mw.tu-muenchen.de>)
Session Scope:
After the Fourth International Symposium on Cavitation (Pasadena, CA, June
2001) where several physical models and CFD tools were presented, it
appeared of interest for our scientific community to better know the
features of the various physical models available for computation of
cavitating flows.
The proposed session is a first attempt to present these models in a
unified way and to start a comparison of the computational results on a
common test case. In a first step, we have deliberately chosen a very
simple two-dimensional configuration for which experimental data are not
yet available. Therefore, this session does not aim at validating tools
against experiment but it simply offers a forum of discussion on existing
physical and numerical cavitation models.More information :

(2)Useful applications of cavitation( Hiroharu Kato
<
kato@eng.toyo.ac.jp>, Allan Acosta <
aacosta@computerfactory.com> )
Session Scope:
Due to the destructive character of the bubble collapse, cavitation is
normally considered to be an unfavorable phenomenon in conventional
engineering problems. However, the same character of cavitation is
beginning to be positively utilized in the following fields. This session
is intended to discuss about recent progress on the new and positive use
of cavitation in the following fields.
OS-2-1: Practical use of cavitation in biomedical field(Shinichiro
Umemura<sumemura@crl.hitachi.co.jp>)
OS-2-2: Practical use of cavitation for environmental control(G. L.
Chahine<glchahine@dynaflow-inc.com>)
OS-2-3: Practical use of cavitation for manufactureing and material
processing(Hitoshi Soyama<soyama@ism.mech.tohoku.ac.jp>)
(3)Cavitation Inception(Knud Aage Moerch<morch@fysik.dtu.dk>)
Session Scope:
Cavitation inception covers the conditions and processes that lead to the
development of vaporous cavities from cavitation nuclei. Papers on all
aspects of this subject, theoretical and experimental, are invited.
(4)Cavitation-induced unsteady phenomena in high-speed
turbopumps(
Takashi Shimura
<shimura@polestar.kakuda-splab.go.jp>
, Luca d'Agostino<luca.dagostino@ing.unipi.it>)
Session Scope:
Cavitation-induced unsteady phenomena often cause dangerous operation of
high-speed turbopumps. For examples, rotor vibration and cyclic stress of
blades are serious problems to be overcome. Topics included are rotating
phenomenon, surge phenomenon, rotor vibration, pressure oscillation,
stress,
acceleration, noise, head characteristics, etc. All topics associated with
the phenomena are welcome. This session aims to collect experimental and
analytical research results and to exchange ideas on suppressing violent
unsteady phenomenon caused by cavitation.
(5)Advanced experimentions of attached Cavitation
(
Mohamed Farhat
< Mohamed.Farhat@epfl.ch>
, Francisco Pereira)
Session Scope:
The physics that governs the incipience and the dynamic of attached
cavitation is
still not yet fully understood.
The pupose of the present session is to provide researchers curretly
working on
physical investigations of attached cavitation to discuss recent advances
related to this area.
The session will focus on advanced experimentation of attached cavitation.
Techniques such as DPIV, embeded miniature sensors, and laser based
technique as well as
any other relevant technique that contributes in a better understanding of
the hydrodynamic
phenomena and the vaporisation-condensation processes may be adressed.
(6)Cavitation in Hydraulic Machines
(
Shengcai Li
< S.Li@warwick.ac.uk>)
Session Scope:
Cavitation and associated effects such as damage, vibration and noise has
always been the main obstacle to the development of high performance
hydraulic machines (turbines and pumps). This session will provide an
opportunity to discuss and exchange information about the progress made
recently in tackling these cavitation problems in hydraulic machines,
ranging from fundamental phenomena to practical solutions involved in the
processes of design, manufacturing and operation. It is particularly
welcome to submit papers on the subject of synergetic behaviour of
cavitation and silt erosion because this is a problem encountered very
often in turbines and pumps but not well understood yet.
(7) Cavitation for High-Speed Motion in Water(
William Vorus
< wvorus@uno.edu >,
Ivan Kirschner
<IKirschner@anteon.com>,
Aleksy Terentiev
< tag@chuvsu.ru>,
Vladimir Serebryakov
<
serebrvv@public.icyb.kiev.ua>)
Session Scope:
Realization of high-speed motion in water is a field where cavitation
phenomena frequently appear and are actually put to use in optimizing a
system design. Both nature or ventilated supercavitation and multiphase
flows can be taken place and applied in this field. Including
considerations of propulsion systems, the occurrence of cavitation in
flows involving surface vessels such as planing boats or hydrofoil craft
and i.e. have be taken into account for speeds as low as approximately 15
- 20 m/s. Proper application of cavitation in the design of high-speed
vehicles allows the upper limit of self-propelled operation to approach
100 m/s or higher. With application of modern launcher technologies,
other cavitating systems can achieve much higher speeds in water - on the
order of 1000 to 2000 m/s. Research, development, and technology
involving cavitation for high-speed motion in water are of interest for
presentation at CAV2003.
