حول قسم الهندسة الميكانيكية والصناعية

تأسس قسم الهندسة الميكانيكية والصناعية سنة 1961 ف وهو من أول الأقسام الهندسية في الجامعات الليبية وواكب القسم تطور الصناعة واحتياجات المجتمع من المهندسين في هذا المجال وعمل منذ إنشاءه على تخريج العديد من المهندسين الأكفاء الذين كانوا حجر الأساس لمسيرة التصنيع والإنتاج.

يضم القسم ثلاث شُعب هي شعبة القوى وشعبة الهندسة الصناعية والإنتاج وشعبة الميكانيكا التطبيقية؛ وتهتم شعبة القوى بكل ما يتعلق بالطاقة وتقنيات استخدامها ويندرج تحت ذلك نظريات وتقنيات انتقال الحرارة وميكانيكا الموائع والتبريد والتكييف ومحطات القوى وآلات الاحتراق الداخلي والطاقة الشمسية وطاقة الرياح وتحلية المياه وآلات الضخ وغير ذلك؛ بينما تختص شعبة الهندسة الصناعية والإنتاج بدارسة وتخطيط وتقييم طرق الإنتاج المختلفة وإيجاد الوسائل المثلى لإنتاج منتج ما مطابق للمواصفات من خلال مراقبة وضبط الجودة في مراحل الإنتاج المختلفة مع القيام بدراسات الجدوى الاقتصادية له؛ وتهتم شعبة الميكانيكا التطبيقية بالتصميم الميكانيكي (الإنشائي) للمنظومات والقطع الميكانيكية المختلفة بالسيارات والمصاعد ومحطات القوى ومصافي النفط وأنظمة المناولة وآلات الإنتاج والإنسان الآلي وغيرها.  كما تعنى هذه الشعبة أيضاُ بدراسة أساليب الحد من تأثير الإهتزازات والضوضاء و تهتم أيضا بوسائل وتقنيات التحكم الآلي والتصميم باستخدام الحاسوب.

Helmholtz resonator analysis

Abstract The contribution of this thesis is to improve the understanding of acoustic dynamics in the audio duct with Helmholtz Resonator (HR). In this project, detail measurements of acoustic in a duct with HR induced loud–speaker at various frequencies have been carried out experimentally. Two-microphone technique have been used to measure the net acoustic power transmission in the duct downstream of HR along with the net acoustic power transmission in the duct without the HR. The acoustic wave signals are traveling in the duct as a plane wave, these waves are generated by a signal generator system with a know wave (sine wave). One of the microphone is located just before the neck–duct interface and the other microphone after the HR in the duct. Five type of necks ( perforated neck length 15cm, perforated neck length 10cm, cone–shape neck, Non- perforated neck length 15cm, Non-perforated neck length 10cm ) and three different material of the bottom wall of the cavity ( Teflon, water and cotton ) have been studied. The best results has a good advantage that by using (perforated neck length 15 cm and 4cm diameter because that reduction of noise has been reached 64% percentage and that value is the highest reduction from all experimenting.

Performance Assessment of a Solar-Powered Absorption System in Libya

Abstract During the last years there has been an increasing consciousness of the environmental problems, created by the use of fossil fuels in electrical power generation consumed by converting cooling systems. In addition, the use of common working fluids (refrigerants), with their ozonedepleting and global warming potential, has become a serious environmental problem. This underlines the need to implement advanced, new concepts in building air-conditioning. The most common global type of thermally driven technology to produce chilled water is absorption cooling. For air-conditioning applications, absorption systems commonly use the water/lithium bromide or ammonia/water as working pair of fluids. The objective of this study is to establish a fundamental basis for further research and development within the field of solar cooling. In this study, an overview of possible systems for solar powered refrigeration and airconditioning systems will be presented. The concept of the ‘Solar Cooling Path’ is introduced, including a discussion of the energy source to the collector. Brief information and comparisons of different absorption refrigeration cycles are also presented. A solar-driven absorption refrigeration system has been selected as a case study for a further detailed investigation. A low temperature heat source can be used to drive the absorption refrigeration cycle, making the system suitable for integration with solar thermal collector. The Transient System Simulation program (TRNSYS) and Engineering Equation Solver (EES) simulation tools are used to model and analyze the performance of a solar-driven absorption refrigeration system. Analysis of the absorption cycle system is initiated by steady-state analysis. A modeling of single effect water/lithium bromide absorption cycle was constructed to study the effect of the operating variable on the system performance and to determine the optimum operating conditions for the absorption cycle. This model was developed by Engineering Equations Solver program (EES). In practice, the ambient conditions and solar radiation are not constant. Therefore, a dynamic analysis is useful for determining the characteristics of the system during the entire year, and dimensioning the important components of the solar collector subsystem, such as storage tanks and collector area. The overall solar absorption cooling system has been simulated by the TRNSYS program with a typical meteorological year file containing the weather parameters for the capital of Libya, Tripoli. Finally, a parametric study was carried out to investigate the influence of key parameters on the overall system performance of solar absorption cooling system and hence to improve and optimize the system design. Results from the parametric optimization indicated that with an area of 130m2 of flat plate collectors with an inclination of 32° and 3.5m3 of storage tank is achieved to cover the demand of air conditioning of a 35kW absorption chiller.

The Effect of Fuel Additives on Spark Ignition, and Their Implications on Engine Performance: An Experimental Study

This paper is designed to present an experimental study being recently conducted for investigating the effect of some fuel additives on the performance of spark ignition within a benzene engine. Three types of additives were added separately (Gasoline Additive, Gasoline Booster, and Octane Booster) to pure gasoline with a volumetric ratio 1:6, 1:7, and 1:8 respectively. Four separate laboratory experiments being conducted using an internal combustion engine at rotational speed ranges from 600 to 3000 rpm, where the three mixtures and the pure gasoline itself were used. The findings showed that there was a positive effect on the engine performance as the brake power increases by 8%, 13% and 23% at the use of Gasoline Additive, Gasoline Booster, and Octane Booster respectively as compared with using only the pure gasoline. The brake thermal efficiency (ɳth) was also affected positively showing its maximum value of about 8% for Octane Booster, and with a minimum value for using Gasoline Additive at about 4.7%. In addition, this study showed that the value changes in the brake specific fuel consumption for Gasoline Additive, Gasoline Booster, and Octane Booster was at the levels of 1%, 2%, and 5% respectively compared with using only the pure gasoline. Furthermore, the results also showed that the use of Octane Booster gave the highest level of air fuel ratio arabic 18 English 97
