  1. Pump Jet Geometry Cheryl Clark, Engr Teacher, Victoria East High Dr. Cable Kurwitz Cheyn Worn, Grad Student, Nuclear Engr

  2. Typical Ejector Pump

  3. Research Objective • Characterize the performance of two-phase (vapor-liquid) flow through an ejector. • Current models assume single phase (liquid or gas) flow. • Two-phase flow is difficult to model • Engineers typically rely on correlations from experimental data

  4. Experimental Procedure • Gather data at different two-phase flow conditions for varying geometries within the ejector

  5. Experimental Procedure • Change the geometry of the ejector • Set the motive fluid flow • Vary the gas to liquid ratio in the suction by varying power to the heater • Data is collected using Labview

  6. Sight Glass

  7. Boiler

  8. Two Phase Flow

  9. Data • Sixteen Instrument Readings: • Pressure • Differential Pressure (dP) • Temperature • Mass flow (suction and motive)

  10. Typical Ejector Pump F,P-HEAT DP-1 DP-2 DP-3 DP-4 F,P-EVAP DP-5

  11. Data Interpretation • Plots made by dumping data from Labview to Excel and Matlab

  12. Real World Applications • Replacement of typical pumps that have moving parts with more passive and reliable ejector pumps • Applications with a need for air conditioning in low power areas such as an airplane on the runway or a vehicle in space (no electrically driven pump) • Utilize benefits of two phase flow

  13. Research Lab • Multidisciplinary • Ejector Jet: Mechanical Engineering • Applications: Aerospace, Nuclear, Chemical, Mechanical

  14. Dr. Cable Kurwitz • Space Engineering Research Center and Nuclear Power Institute • Doctorate in Nuclear Engineering • Licensed Professional Engineer • Wide Array of interdisciplinary subjects • Director of Systems Engineering Initiative

  15. Summary • Gather experimental data on two-phase ejector jet operation • Wide variety of applications • Air condtioning systems • Vacuum distillation • Optimal mixing • Replace typical pumps
