In electron-beam machining (EBM), electrons are accelerated ..
In electron-beam machining (EBM), electrons are accelerated to a velocity nearly three-fourths that of light.

The process is performed in a vacuum chamber to reduce the scattering of electrons by gas molecules in the atmosphere.

The stream of electrons is directed against a precisely limited area of the workpiece;

on impact, the kinetic energy of the electrons is converted into thermal energy that melts and vaporizes the material to be removed, forming holes or cuts.

IDENTIFICATION OF UNDER WATER VEHICLE HYDRODYNAMIC EFFICIENTS USING FREE DECAY TESTS



INTRODUCTION
In recent years there has been an ever increasing number
of applications for unmanned underwater vehicles
(UUV) in various tasks, for instance in surveying and
exploration, or in missions such as the positioning
of underwater laboratories (Aguiar 1997). Improvements
in the evaluation of the hydrodynamic models
of UUV’s result in more effective control s ....etc

hello sir,
i am gokul venugopal doing final year b tech in mechanical engineering here itself.now i want to do a academic seminars.our seminar co-ordinator approved me the subject super cavitation.i collected simple notes from wikipaedia.but its not enough,its simple notes.so i want much more details about super cavitation for my seminars.it is very helpful if i get that in the pdf format in the seminar report model.can you help me for getting the details.

thanking you,
gokul venugopal ....etc

introduction
 The magnetohydrodynamic propulsion is a new propulsion system which is used for propelling ships & submarines.
 The magnetohydrodynamic, or MHD, propulsion has no moving parts like propeller, gear, shafts etc
 Submarines fitted with it , cannot be detected easily
(as it is silent)
History
 First proposed by W A Rice in 60’s in USA
 He does experimental work on it using dc direct drive propulsion using battery driven magnets
 Speed 1.5 ....etc

Abstract:
The problem of possible pitting and cavitation in internal combustion engines is
receiving Considerable attention. Both theoretical and simulation simulation studies
are carried out in order to understand the noise and vibration sources, using a force
equation. Both theoretical simulation and simulation studies are carried out in order to
understand the noise and vibration sources, using a force equation.For this work ....etc
