Abstract:

In this study, it is aimed on to investigate effects on ejectör the flow characteristics of ejectors used in the absorption refrigeration systems. Results are expressed as contours for pressure, temperature and Mach numbers in the ejector, distributions for the entrainment rate and pressure throughout the ejector axis using five different working fluids, amonia-water, carbondioxidewater, amonia, R134a, R141b via Computational Fluid Dynamics Package, Fluent. The analyses are based on the assumptions that the adiabatic and isentropic conditions exist.
