Abstract
This work reviews the current operational condition and activities on design modification for different applications of ejectors. Ejectors being a simple mechanical system capable of performing multiple fluid related functions (vacuum generation, pumping, mixing, condensing and heat exchanging), have been an essential part of several industrial processes. Two areas have been emphasized; internal flow and application-based modifications in components of ejectors. The geometry and inlet flow conditions were found to be the prime influencing factor of its performance. The objective and application-based modifications were performed on the primary nozzle, secondary nozzle, mixing chamber, throat and diffuser. The resultant performance was found to be dependent on operational condition and fluid type. This emphasizes the requirement of application-based design selection of the technology. In addition, the flow dynamics of condensing, non-condensing, particle and slurry flow has been studied based on available literatures. The one-point final objective is to identify the usability of primary water jet ejectors for active vapor transport and condensation, to replace vacuum pump and condenser in compact domestic water desalination system.
Highlights
Modern day technology focuses on the improvement of process or product, from a sustainability perspective, to have persistent present enrichment, for the future
The prime objective of this study is to make a collective summary of progress on design criterion and its optimization associated with ejectors
We examine industrial problems associated with the ejector application
Summary
Modern day technology focuses on the improvement of process or product, from a sustainability perspective, to have persistent present enrichment, for the future. Sustainable engineering designs system and process, which uses energy and resources with positive assurance towards environment, economic and social challenge [1]. Water stress and waste heat recovery are two separate global concerns. The developed system has positive assurance on environmental impact, energy efficiency and economical water production prospects. This is a technology-based review on the technical capability and extent of ejectors for developing ejector-based water desalination systems using low grade (industrial waste/solar) heat sources
