Özet

Steam ejectors are one of the key components of steam ejector refrigeration/heat pump systems. Steam ejector is required to compress low-pressure stream to a higher pressure. Steam ejectors have no moving part, a simple structure, low cost, reliability, easy installation, high vacuum performance, corrosion resistance, and no consumption of electrical energy. In this study, steam ejector design was modeled using finite volume techniques, and Mach number and pressure in constant cross-section have been compared with analytical data reported in the literature. In this work, numerical calculations were performed with ANSYS Fluent(ANSYS FLUENT Theory Guide, ANSYS, Inc. Release 17.2, 2016, Canonsburg, PA, USA), a computational fluid dynamic code. In the turbulent flow, heat transfer-based analyses were performed using energy equations.
