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
Experimental Procedure • Gather data at different two-phase flow conditions for varying geometries within the ejector
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
Data • Sixteen Instrument Readings: • Pressure • Differential Pressure (dP) • Temperature • Mass flow (suction and motive)
Typical Ejector Pump F,P-HEAT DP-1 DP-2 DP-3 DP-4 F,P-EVAP DP-5
Data Interpretation • Plots made by dumping data from Labview to Excel and Matlab
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
Research Lab • Multidisciplinary • Ejector Jet: Mechanical Engineering • Applications: Aerospace, Nuclear, Chemical, Mechanical
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
Summary • Gather experimental data on two-phase ejector jet operation • Wide variety of applications • Air condtioning systems • Vacuum distillation • Optimal mixing • Replace typical pumps
