Characteristics of HQ Tube for Turbofan Engines

Abstract The contribution of this thesis is to improve the understanding of acoustic dynamics in the audio duct with HQ (Herschel-Quincke tube) is essentially a hollow side-tube that travels along a main-duct axis and attaches to the main-duct at each of the two ends of the tube. In this project the detailed measurements of acoustic in a duct with HQ induced by a loudspeaker at various frequencies have been carried out experimentally. Two microphones have been used to measure the net acoustic power transmission in the duct downstream of HQ and compared with the net acoustic power transmission in the duct without the HQ. Two types of HQ and three different ducts have been studied. The acoustic wave signals are traveling in the duct as a plane wave these waves are generated by a signal generating system with a known sinusoidal wave (sine wave). One of the microphones is located just before the HQ-duct interface and the other microphone after the HQ in the duct. Labview software is used to analyze the signals with a sampling rate of 44100s/sam and number of samples is 20000. This study makes an exhaustive understanding of power spectrum of two acoustic channels in the duct with and without HQ. The results show that there is a great potential for HQ tube system to attenuate the noise over conical and cylindrical sections. The sound attenuation on conical section with short HQ shows about 70% and that of cylindrical section a meager 47% at higher frequency. Further more the sound attenuation of cylindrical section with long HQ is occurred at low frequencies.

Voltage stability of the Libyan network after its enhancement by new stationary and mobile units and new 220-400KV transmission Lin

Abstract The conflict that took place in Libya in 2011, up to the present moment, has greatly affected the electrical power network and resulted in the rise of the voltage instability problem. This was due to loss of the some major transmission lines and certain generation units. Owing to the fact that the southern region of the Libyan network has no generation units, voltage drop phenomena has become a common problem as a result of the long transmission distance, which is approximately 750km. A proposed solution in order to solve this problem is via the utilization of small mobile generation units at the network weak points. This thesis revolves around discussing the voltage instability problem within the Libyan Network and how it can be enhanced when small and mobile generation units are connected to the network weak points. It will also establish and identify where the most weakened buses and regions are so that the mobile units should be connected for the attainment of optimized solution. Moreover, this solution was proposed as it can solve not only the voltage instability problem, but it will also solve the inadequacy in generation issue by circulating additional power within the network. Hence, reduce the load shedding phenomena. Furthermore, the thesis also includes future recommendations to improve and enhance the Libyan network by the addition of new 220kV and 400kV transmission lines that will enable the network to cope with the load growth in the future

دراسة هيدرولوجية لحوض وادي الزغادنة

Abstract this study aims to investigate the hydrological cycle at wadi Zaghadnah basin in Tarhuna in terms of (rainfall-surface run-off-evaporation-infiltration) and estimation of the quantity of surface water , and to predict the maximum flood can happen in order to reduce hazardous to houses and farms that are found on my profile of the valley was the use of a series of years of readings rainfall and results have indicated to the fact that annual average rainfall was (238) mm, via using (Isohyetal method).The quantity of water which is supposed to be reserved in the dam was (1.94) million cubic meters. As for rain test, it was found that it is random and non-coherent. Having studied rain-wave relation through application of modelprediction statistical, it was deduced that it is not reliable to depend-upon in forecasting the expected rain. Results have indicated that total evaporation average to (2324.5)mm via using (CROPWAT) and average annual infiltration is (2065.17)mm, and post application of some statistic equations like probability log-Pearson Type ׀׀׀distribution and Gumbels distribution-plotting (25-50-100-1000), maximum possible amount (via using the aforesaid three methods) was found, but due to silt and likely erosion of soils as a result of flooding, silt amounts in Dom lake was estimated by using calculative equations was (5622)m³/year.
