One of the issues that need to be addressed in order to improve the durability and efficiency of a PEM fuel cell system is the management of the hydrogen feeding procedure. It has been demonstrated these aspects are improved when a hydrogen recirculation systems are used [1]. In this work, an ejector has been designed and manufactured and implemented in an experimental PEM fuel cell Test Statio...

Ejectors are a kind of pump that does not have any moving components. In certain cases, the motor fluid may be liquid, steam, or another gas. The research focuses on using nano adsorption combined with multi ejector to fuel sophisticated power plant, which is equipped three shapes steam boiler generators. simulation was accomplished by implementing it cooperation two programs MATLAB A and B, to...

Optimization of a High-Efficiency Jet Ejector by Computational Fluid Dynamics Software. (May 2005) Somsak Watanawanavet, B.S., Chulalongkorn University Co-Chairs of Advisory Committee: Dr. Mark T. Holtzapple Dr. Charles J. Glover Research was performed to optimize high-efficiency jet ejector geometry (Holtzapple, 2001) by varying nozzle diameter ratios from 0.03 to 0.21, and motive velocities f...

In recent years, there has been great interest in developing cooling systems with humidity- and temperature-independent control capabilities that can operate efficiently at varying temperatures. This paper proposes a bi-loop double-evaporator ejection–compression cycle, which utilizes low-grade heat is suitable for the construction industry. The proposed cycle involves concurrent operation of v...
