The objective of the analysis was to find the optimal intake area for stoichiometric combustion. Mass flow rates of propane through the ejector were calculated for various input pressures through Bernoulli approximation. These values were used to calculate required intake area for stoichiometric combustion based on the assumption that air and fuel velocities would be equal. From these analyses, it was concluded that the intake area would be the same for any input pressure. Intake area was the The final approach for finding the optimal intake geometry was based on a ratio between the propane ejector outlet area and the air inlet area. This approach was discovered in “A Simple Method for the Design of Gas Burner Injectors.” by CJ Lawn. This ratio was calculated based off of the desired air/fuel ratio and the density ratio between air and propane. This approach was compared with flow rate analysis at various propane pressure settings. The result of this calculation is that for any set propane pressure, the height of the intake opening needs to be .232 inches high. All green sheets for this analysis is shown in Appendix A of the Final Report.
