CFD Optimization Study of High-Efficiency Jet
Ejectors. Edition No. 1
VDM Publishing House, Feb 2009, Pages: 308
Research was performed to optimize the high-
efficiency jet ejector geometry by varying motive
fluid velocities and mass flow ratio. The high-
efficiency jet ejector was simulated by Fluent
Computational Fluid Dynamics (CFD) software.
In the optimization study of the constant-area jet
ejectors, all parameters were expressed in
dimensionless terms. Dimensionless group analysis
reveals that the research results are valid for any
fluid, operating pressure and geometric scale for a
given motive-stream Mach number and momentum ratio.
The results from the optimization study indicate
that the jet ejector efficiency improves
significantly compared to a conventional jet-ejector
design.
The results also show that substituting a single
optimal jet ejector for a single conventional
ejector reduces the motive stream
consumption by about 10% to 30%, which could
decrease operating costs tremendously.
The explanation of how to implement the optimization
results and selecting the best operating conditions
to minimize the motive stream consumption was
included at the end of the dissertation.
