Kompletní popis

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.
