Abstract
The objective of this thesis is to design an economically and
environmentally acceptable alternative system to transfer sediment sand in the
bottom of waterway Channels for the purpose ’of dredging or sand bypassing by
fluidization and jet p._. Also, a theotetica! formula had boen detived to
predict jet pump performance under various working conditions using basic
fluid mechanics: equations (continuity, momentum and energy equations).
The thesis includes investigation about the perfonnance of jet pump
•
under the effect of some parameters such as: area ratio, mass flow ratio, driving
nozzle to mixing chamber distance~ suction inlet configuration and speed of jet
pump when moves during operation. A special experimental test rig has been
designed and built to study the effect of these panunetets experimentally, A set
of experiments were carried to cheek the validity of the theoretical formula to
predict jet pump performance and to examine some of alternatives of jet pump
parts that give the best performance.
from the experimental work the best values for design parameters have
been obtained. Further, the experimental results are compared with the
theoretical results and the other previous works, which showed a relatively good
agreement.
