Abstract: Jet pumps have been widely used in many applications such as water desalination, steam turbine power generation, refrigeration systems, and chemical plants. The advantage of jet pump system lies in its extremely reliable and stable operation due to the complete absence of moving parts. The performance depends on a number of factors, However among which the flow channel configuration. To obtain this better performance at different operating conditions, area ratio of the jet pump is varied. In this study, a new diffuser based on constant rate momentum change method jet pump theory is written to analyse performance of the proposed jet pump. The model based on the axis-symmetric representation of the experimental jet pump is created using Computational fluid dynamics. The analysis includes effects of pressure and the effects of velocity in the mixing chamber and in the diffuser. The simulated performance of conventional and modified jet pumps are compared. The effects of operating parameters of constant rate momentum change jet pump and conventional jet pump on entrainment ratio are studied.

Abstract: Cellular communication has brought in an unparalleled revolution in the field of communication during the past two decades. The mobile communication industry growth has surpassed growth of all other fields. Even our own country is not left behind. We are led to important conclusions by comparing the two main technologies costs and evaluating the cost parameters and variables that will lead future researchers to suggest ways to reduce the higher costs. The number of mobile subscribers in the country rose to over 911 m in Mar 2012. 3G system has been introduced in line with other countries. Talks have started about 4G / 5G. The implementation of 4G /5G will most probably be the ultimate goal in the field of communication.
