| Summary: | This report is a write up on what the author had learned and done during his Final Year
Project period. The first part of this report will give you an idea why variable area ratio
ejector was used in EMERS.
After which will be analysis of experiment's data. At the end of every experiment, there
will be a conclusion followed by what is the next procedure to be executed.
Through the experiments, the author had gained knowledge on how varying the spindle
position affects the pressure, flow rate and pressure recovery in an ejector. Author also
found out that for a certain range of spindle position, pressure and flow rate were not
greatly affected. Effective spindle position where significant change in pressure and flow
rate was been explored. Furthermore, changing one of the parameters other than EEV2,
the secondary inlet pressure of the ejector can be manipulated. Lastly, a model relating
the pressure change, mass flow rate and spindle position was proposed. |
