Analysis and Design of a Steam Ejector Structure
By adjusting structures of the nozzle and mixing-chamber , effects of the structure on the steam ejector performance were analyzed. An improved CFD program which was proved suitable for simulating flow profile in a steam ejector formerly was used here. The results of this study would be useful for designing a steam ejector with high performance when working condition was given.
An exergy analysis of a solar-driven ejector refrigeration system
Energy analysis is used as a tool to analyse the performance of an ejector refrigeration cycle driven by solar energy. The analysis is based on the following conditions: a solar radiation of 700 W/ ...
Frequency selective surface design for blinds applications
In this paper, the reconfigurable blind structure with frequency selective surfaces(FSS) for the building applications are presented. Frequency transmission characteristics for different angles of the proposed blind-FSSs are investigated and verified through simulation and measurement. The simulation results show that we can implement the reconfigurable blind-FSS for multiband wireless applications. To verify the proposed paper, two kinds of blind-FSSs, crossed dipole FSS and circular ring FSS are fabricated and measurements are performed for different angles. The proposed structure in this paper which is very simple, can be easily applied to any planar surface for wireless security applications at low cost.
