Abstract

Numerical investigations have been carried out on water ejector employing water as a working fluid. The effect of the convergence nozzle angle on its efficiency was investigated. The nozzle convergence angle in this study was varied as 12°, 14°, 16°, 18°, and 20°. Validation is achieved on selected test cases by the comparison between numerical simulations results and experimental measurements. The numerical results were found in good agreement with the experimental results. The water ejector with the nozzle convergence angle of 12° has the maximum efficiency.
