Abstract: A complete numerical model has been developed to characterize the performance under different flow conditions. Finite Difference-based method was used to analyze and simulate flow behavior inside ejector pumps for both single phase and dual-phase fluid flow. Single phase model of ejector pump only has one fluid as inputs and its performance is well understood. The behavior of a single phase flow inside ejector pumps have been investigated both analytically and experimentally. Dual phase flow got very few attentions from past researchers. The present work addresses these problems numerically using Finite Difference Technique. Both single and dual phase flow are investigated for comparison. Finally experimental verification of the developed numerical methods is done on an experimental rig developed at our systems Engineering Laboratory. The tests will under different input pressures in order to characterize ejector pump performance. Results obtained numerically for single phase model have been compared with experimental data obtained in separate study at MU. The predicted pressure distribution within the ejector pump and performance curves matches the experimentally observed ones. Results obtained numerically for dual phase model were effectively used for prediction of energy, pressure and velocity changes through the ejector.
